Question

Posted

My story is; I had an Xperia arc (not the arc s) and on both GB and ICS I could use it for about a month or three before it would gradually degrade into becoming utterly useless due to the massive amounts of lag. It got so bad that it was impossible to answer a call because the slider to answer was unresponsive. I wish I was kidding.
A similar situation occurred with my first Xperia, the Xperia X10i.

I ended up getting a 2nd hand iPhone off eBay and have been using it for about 6 months now with no lag issues of any description.

I don't remember exactly what apps I was using, but I don't believe that it should be my responsibility to go through extra steps to close an app when the iOS memory management (or whatever the balls is controlling that) seems to be able to handle me opening a bunch of apps without bogging down the phone.


I saw the new Xperia Z and it is pretty damn sexy, but I'm extremely gun-shy about going back to Android due to my above experiences. I'm tired of my phone looking like a featurephone in terms of the UI, the poor performance of Chrome Mobile and the inability to set Chrome Mobile as default browser, but I can live with that if it means I have a working phone when I need it to be a phone.


I'd like to hear from people whether JB has improved UI responsiveness even during heavy use, whether low signal areas still drain 30% battery in the same amount of minutes, and whether the general battery life has improved (I realise this is very subjective based on usage).

Thanks in advance :)

Yeah, I've heard the bit about iOS multitasking - IIRC apps can request to run for up to 10 minutes after they've been "closed" (brought out of focus), and they can only register to receive / display Push notifications past that limit. I'm not entirely sure if I see the benefit of having an app actually running perpetually in the background, though. Then again, I'll freely admit that my ability to think outside the box for these things is quite limited.

I wish it was easy to use the stock UI while still having display enhancements like the BRAVIA Engine and such - from my understanding they bake it into the kernel or other system files...

I guess I'll wait for the phone to come out and get someone to tell me the kernel it's running at and such before making a decision. My contract doesn't expire until the 26th of March anyway.

The Xperia Z is a true powerhouse, you should go for it imho. The OS/kernel won't be a problem and you'll have a Jelly Bean 4.2 upgrade soon afterwards. It uses kernel 3.4, the same version used in the Nexus 4 and Xperia T.

That is apps in the background disappear from memory when they haven't been accessed for some time and have to be reloaded. There are probably lots of different things going on under the hood.
[/quote]
This has always been the case, [i]inactive[/i] background Apps which are no longer used will automatically be killed after some time though they will still appear in the recent apps window hence require reloading if switched to. Active background apps will remain in memory unless the device runs out of RAM, in that case the memory manager will start terminating them starting with the low priority background processes.

Generally speaking, its app updates that tend to cause Android to slow down. Sometimes fixing the problem is as easy as wiping the dalvik cache and letting the apps be re-optimized on the next boot. The issue is similar to slow downs caused by Windows registry fragmentation that used to plague Windows XP.

I've had no end of problems with my Nexus 7.. lots of random reboots, crashes, sometimes it'll just sit there rebooting for hrs.. and that's with it relatively clean, as I nuked it not that long ago.

My Android 4.0.3 on Sony Tablet S slows down over the course of 6 months. I have had to reinstall it once already. Luckily for me, my Google Account does the backups so when I signed in, everything came back. Just had to reinstall several programs. Reinstall took about 15min.

The software can depending on how much your carrier screwed with it. The beauty of Android is you can flash something like CM10 or MIUI or AOSP or AOKP roms and get more...

Not sure if that was directed at me - if so, I think you must have missed the promotional video for Project Butter where they showed how the UI used to lag. My issue was basically the same, only it got progressively worse as time went on until the phone became literally unusable as a phone.

If I had asked "does Project Butter work as advertised?" I bet I would have gotten a lot more "yes my phone is fine" posts and less posts like yowanvista's posts that helped me gain an understanding as to what exactly is going on and why it's much less likely to be an issue on today's kernel / hardware.

That's not to say I don't value people saying their phone is fine - I do, it's always good to hear that it's not an issue affecting 100% of users. But it's also nice to hear from people saying "my <phone comparatively aged to mine> used to do this but once I got one with decent amounts of RAM it's been fine" since that inspires confidence :)

I've always de-branded my phones - Manufacturer's flaky update schedules are bad enough, I don't need my carrier slowing it down further ;)

But then again, the beauty of iOS is that once I see on Engadget a new iOS version is out, I can get it too, and it's always OTA as well :)

I also get random crashes, even with stock apps.. like Chrome..

Though since I got an iPad Mini, I haven't really messed with all that much.. I really should RMA it and see if maybe it's hardware..

The problem usually is that you keep on stacking up new apps and more apps that keep doing more in the background. Doing a clean install every X months isn't such a bad idea.

In general Android is pretty robust though. I've had an Arc, Arc S, Neo, S and T for quite a while and with every generation the effect got much less bad. Before switching to the T I'd been using the S for about 6 months without a reinstall and it really did fine. No slowdowns at all.

I've now also placed my pre-order for the Xperia Z :) It looks like a kickass phone, and with 2GB RAM you just can't go wrong.

I started off with in Android with a Nexus One, then a Samsung Galaxy S, then a Galaxy Note. All without much issue. Any issues I have had were attributed to bad ROM developers. Just had to find a suitable ROM and it's been smooth sailing. Even my Nexus One has ICS on it. Haven't tried to put JB on it yet.

I had a Droid DNA for about a week, and Android bogged down so badly on the "Worlds most powerful superphone" that I got rid of it. It was bad enough everything felt disconnected from everything else, but it was laggy, unresponsive at times, and once you had 1-2 apps open, it ran horrible.

I generally have 4-5 apps open on my nexus 7 and it's always smooth.

That is certainly not normal, i've never seen any crashes or random reboots on my nexus 7. Sounds like its defective of its 'rebooting for hours'...

It's not as bad as what it might appear from the OP's text, but my Arc definitely performed poorly cause of outdated specs

My Galaxy Nexus does this (running ICS 4.0.4), runs smooth and over time becomes incredibly laggy to the point it's nearly unusable. Even Jelly Bean (4.1, custom ROM) over time lags like crazy on my Acer A500 (not sure if the ROM is at fault or faulty hardware on the tablet). So Android is still an extremely laggy experience for me (what doesn't help is that fact iOS runs silky smooth on my gen5 iPod touch, never lags....so going back to my laggy Android is hard sometimes :laugh:). I really hope 4.1 fixes the lag issues on my Galaxy Nexus, that is if it ever gets released (my Galaxy Nexus is carrier locked and they are sitting on the update, claim they found a serious bug in it) and yes I know I could root it, but to make it work properly on my carrier would involve alot of fiddling which I can't be bothered doing :p

Absolutely it does. And before the pathetic fanboys come out and flame me, I've owned more Android devices than anything else.

Galaxy Nexus did.

Galaxy S3 did. S3 was the friggin worst.

Yeah I accept that, since I don't remember what apps I was running, I may very well have installed something that had bugs in it causing this to occur. But the point remains, iOS has not degraded in a similar fashion despite similar usage patterns. Whatever the cause, I hope that if I do take the plunge and go with another Android device, it won't suffer similar issues.

It almost entirely depends on how many and which apps you install. If you have 100 apps that all think they need a background process, then yes, you're going to see a slowdown. I generally run a handful (10-20) apps and some small games usually of the words with friends or scramble with friends variety, and I haven't had lag on the latest generation devices. I don't think I could make my One X lag if I tried. Older phones like my Captivate were definitely slower though, but again, the only relation to how long it had been since I'd factory reset would have been how many apps I had installed. Regardless, smooth then was nothing like smooth now. Project Butter really helps to smooth out the whole experience.

Put it this way, I've never found any of my Android devices to be any more or less laggy than iOS devices of the same time frame. The iOS fanboys just like to act like iOS never lags. I had a 3G a long time ago and it had horrible lag sometimes. I had an iPhone 4 and it was much better, but it too lagged now and then. I haven't had extensive experience with the iPhone 5, but I suspect, like Androids on current hardware, it would show very little to no lag. The reason it would have been more noticeable on an Android is because of the multitasking and allowing apps to freely run their own services. I think these features are major advantages of Android, but they aren't without some performance impact. That's why Apple is always able to include slower CPUs and less memory in the iPhone comparatively.

I'd really say that smart phones have only just matured in the last year or so. Prior to that, new features were being rolled out as fast as performance was being improved, especially on a mobile OS like Android that has more extensive multitasking and such. Now that mobile CPUs have gotten so fast and large amounts of memory are being included, lag isn't really much of a factor on more new phones from any manufacturer or type.

Most useful, since indeed there's been quite literally a quadrupling of power (single core 1.5 GHz to quad core 1.5 GHz, 512 MB to 2GB of RAM) between my previous venture into Android and the phone I'm looking at :p

I know that the iPhone 4 (my current phone) lags like an asthmatic ant when I try to do fast browsing in Chrome Mobile, and I've figured out that mobile browsing with Chrome, Kindle and various social media clients are the primary usages of my smartphone. I don't mobile game - I always have something to read on the go, and so I need a phone that gives me the best mobile browsing experience with Chrome Mobile.
Why Chrome specifically? Because of the tab syncing, I need to be able to see my tabs from my phone on my desktop / tablet.

That's why I'm looking at a whale phone (5in) :p

A friend at work mentioned something to me the other day that I had never heard before. Apparently the manual of his Droid 2 said that you are supposed to reboot the phone once a day, I assume to reduce lag. I've had both my phone and tablet bog down, but that was only when I was running a lot of heavy apps simultaneously. Once I close a few apps, the device becomes just as snappy as it would be on a fresh boot. Both my phone and tablet are rooted, running ICS and JB, respectively.

I'm still running Android 2.3 on my old HTC and have never had a problem but a friend of mine has the exact same phone and has had nothing but problems with bogging down. Not sure exactly what it is.
[/quote]

There are multiple reasons why this happens.

It comes down to:

1. Apps you install. If an app you installed has memory leaks (aka not coded right or has a bug that causes that memory leak) only that one app can cause your phone to become unstable as it will eat your memory. Unlike iOS, the thing with Android is that it is a true multitasking OS. This means that your apps runs as a process in the background and can execute things. iOS kills apps completely after you switch away from it, so the app can't do anything when it's in that state. It's a bit more complex than that but that's basically the gist of it.

2. The ROM version or custom ROMs might also have memory leaks themselves. Especially in launchers they put on top and that could be the cause of instability. At first everything runs great, but after time your OS gets out of memory and it starts closing processes and just becoming unstable. That's when you get those WAIT or CLOSE PROCESSES dialog.


For those who have issues my advice is when your Android device starts lagging, go to Applications and you will see processes there and how much memory they consume. You can spot which apps have memory leaks and just kill those and don't run them or if you do, make sure you close their process after you are done with it.

Yeah, I know it's really easy to root the phone but that isn't the problem. Stock Android (on the Galaxy Nexus) doesn't work well with my carrier without tweaking it (need to replace the radio and change some other stuff) because my carrier insists on using the obscure. This in turn breaks the auto updating and means you cannot update to the newest version of Android, as Google pushes it out, without breaking the phone again....it's a nightmare from what I've read and I just can't be bothered with all the extra stuff you gotta do to make it work right again. Is my excuse anyway :p

Yea, for me I tend to notice a slowdown/lag over time (probably more to the 6 months or longer) because I am one of those people with 200+ apps installed, and many running quite often, and the phone never turned off. So I expect things like that, wish it didn't make a difference but it does. Well I shouldn't say that, with each new generation it gets less and less.
