Hi,

 

I have a MacBook Pro (Retina, 15-inch, Mid 2014), and for a while I have been noticing my battery life is significantly lower than advertised. Here are some of the things I usually do on battery:

 

1. Write articles, books, blog posts, etc.

2. Surf the internet, etc.

3. May be watch movies or something.

 

When I run Google Chrome browser, it takes up a lot of power. So, I switch to Safari when I

Thanks for your feedback all. Little bit of Googling pointed me to 'Calibrating the better in a portable Mac'. I did everything the article said yesterday, and to my surprise, my MacBook now says it has 5:30 hours remaining!! I gained 3.5 hours of battery life just doing this. Not sure what calibrating really does but it did boost it up significantly. Apparently, the article says that we should calibrate the battery right after purchase and every two weeks. The remaining battery life is increasing as I'm writing this reply :D. Hopefully it will hit 8 hrs :p

It might have said that, but what was the real world performance?

So far it's going great! Before calibrating the battery, it would deplete very quickly. The charge remaining now says 7.5 hours! All I'm doing is basic surfing, checking mails and some writing. Let's see if it stays up to 7 hours as it calculated. And the brightness is set to 2 ticks above the mid-point, I guess somewhere around 70%.

Yes, keep us updated.

 

I am curious.

Two hour battery life is completely unacceptable and is not what a macbook pro is known for.  I have a mid-2013 rMBP and mine routinely gets 6 on a full charge.

 

I have time machine, crashplan, teamviewer, sophos a/v, onedrive, 1password mini, wifi, and bluetooth all running in the menu bar.  Not to mention any programs being used.

 

If you are only getting 2 hours then you have a much bigger issue going on.

Chrome is one of the biggest power hogs for some reason on a mac, thats part of it. 

Do you have graphics switching mode turned on so it switches to the on board video on battery? 

 

My 2011 MBP ranges from 4.5 hours of battery to 2hrs depending on what I'm doing and still on the original battery

Depends on what app you're using to write with. I usually have my display nearly up all the way and just browsing with Safari I get at least 6 but then again I usually have a bunch of other stuff opened. Brightness is not going to be your friend if youre wanting long battery life

      Likely nothing will be done in corporate America, there have been countless Tesla self-driving incidents. Then again, there have also been countless human operated incidents. It's literally daily news here in Canada, to the extent that it's now odd if we get a day where a collision doesn't get announced on the radio throughout the day...
    • SKG Hand Massager with Heat OS500 hands on

      By Steven P. · Posted

      SKG Hand Massager with Heat OS500 hands on by Steven Parker I was offered the chance to test out the SKG Hand Massager with Heat OS500, and full disclosure, they let me keep it regardless of my findings. Anyway, I jumped at the chance due to my long hours sitting at my desk, mousing around. Apologies for the knife cut across the top of the box; that was my doing, being a bit too heavy-handed with opening up the outer packaging. First up, what's in the box: SKG Hand Massager with Heat OS500 1x Type-C charging cable User Manual 1-Year Warranty (card) In short, everything you need to get started. According to the official Amazon listing, here are the key features: Full-Hand Air Compression: OS500 wraps your fingers, palm, and wrist with multi-chamber air compression for a complete hand relaxation experience. The extended massage chamber helps cover more of the hand and wrist area than standard palm-only hand massagers Palm Kneading with 6 Modes & 6 Intensities: Built-in palm kneading rollers add a hands-on massage feel, while 6 preset modes and 6 pressure levels let you choose the comfort level that fits your day—from gentle relaxation to a firmer full-hand massage 3 Heat Levels with Cooling Fan: Choose from 104°F, 113°F or 122°F warmth to suit different seasons and comfort preferences. The built-in cooling fan helps reduce stuffiness during heated sessions, keeping your hand feeling fresh and comfortable Easy Visual Display & Smart Timer: The digital image display clearly shows massage area, mode, intensity, heat level, and remaining time at a glance. Select 10, 15, or 20-minute sessions for quick office breaks, evening relaxation, or everyday hand care Rechargeable, Cordless & Comfortable: A 3000mAh battery supports over 90 minutes of full-function use on a full charge, with convenient USB-C charging. The soft inner lining, smooth ABS/PU finish, and premium black-gold design make OS500 ideal for home, office, or gifting With all that out of the way, here are my own findings. I gave it a try on both left and right hands, and as you can maybe see from the above YouTube Short, (sorry for the shaky video), my whole hand fits in, but my wrist barely enters the Hand Massager. I was able to push through a bit more with my fingertips extending out the other end to get a bit of massaging on the start of my wrist. Usage For some reason, there is a strap that is very difficult to fasten to my wrist with one hand. I am not sure what function it has, and it isn't mentioned in the user manual. The only thing I could find was in the product images that claimed "wrist precision". Unlike the Bob and Brad Hand Massager, this device does not massage the wrist anyway, even though a "wrist mode" is mentioned, which must be for smaller hands than I have, as it is mainly intended for the hand and fingers. In addition, for its steeper price, there are no disposable gloves provided in the box, which is a bit of an issue considering the internal cover (which appears to be elasticated nylon) cannot be removed for washing; so you are left with only one choice: always thoroughly wash your hands before using it. I can imagine this thing getting a bit grimy after a period of use, and that is a bit of a shame. With that said, the buttons on the device, from left to right, do the following: Heat button: 3-level heat control at 104°F, 113°F, or 122°F Mode button: Auto mode Circular mode Soothing mode Relax mode Palm and fingers mode Palm and wrist mode Intensity button: from (First-time users) 15Ka, 25Ka, 35Ka, 45Ka, 55Ka, 60Ka (Intensive relief) Knead button: on or off (6 pressure levels) Power button: Long-press to turn on or off Cooling button: turn on or off the cooling fan Also, in the product imagery, it states there are 36 "custom modes," but nowhere is it listed what these modes are. I can only imagine that they mean a combination of all of the above settings in different intensity levels. The device itself seems to rely on a single "kneading" mechanism located at the palm area of the hand, which spins when in use, and the other massage features are mainly utilized through the air sacs, increasing and decreasing at various levels on the hand and fingers. I am not sure it offered too much relief for someone who is typing and operating a mouse for hours at a time; further testing may be required. It does feel nice, though. Finally, you may be wondering how this fits into the scope of a tech website? Well, let me tell you something: sometimes I sit for up to 15 hours working on Neowin, and although I take breaks in between, it takes a toll on my body. I think in the immediate absence of a partner to apply relief, a good massager like this Hand Massager can shed the strains of the day in just a couple of 15-minute bursts. On the official website, this has an MSRP of $99.99, but luckily for our readers, it is selling at $10 off for just $89.99 right now on Amazon. SKG Hand Massager with Heat OS500 for $89.99 (with $10 off coupon), $99.99 MSRP For me, this gets a thumbs hands(?) down. However, it could be improved by making it so that the protective covering could be removed and thrown into the washing machine, or get yourself some disposable gloves to use with it.
