I've purchased a Lenovo ThinkPad S540, which has according to Lenovo '9 hours of battery life'. I was really happy when I tested the device running Windows 8.1, and the battery worked for 6 hours. But as soon as I installed Ubuntu 14.04 on it, the battery got a maximum of 2,5 hours. Why is the battery life so bad with Ubuntu 14.04?
First, here's the constants: I keep wifi/BT/GPS on 100% of the time. This was true when battery life was good, and now that battery life is bad. Disabling these will improve battery life, but will not fix my problem.
When the phone is sleeping overnight, I used to get 8-12% battery usage over about 8 hours.
I know we have a lot of battery life threads and I absolutely love this phone but mine is not getting good battery life. I'm an advanced android user, I know it well and I do know that some devices just have bugs which kill battery life.
In the course of testing smartphones, weve come across a curious consistency. On our battery life test, T-Mobile phones tend to outlast the same devices from other carriers, sometimes by more than two hours.
The HTC One X suffered a humiliation in the video playback part of our test. The Galaxy S III put the superior power efficiency of its screen to great use here and took a minute over 10 hours to deplete 90% of its battery.
I just my Note 4 a few days ago. On my battery life screen, the more it is charges, the lower the battery life shows. Example...when it it charged to 98% my battery life shows 5 minutes but when it is at 25% it will show something like 1 say, 15 hours. It's like the battery life time
As we all anxiously await the November 13th arrival of the Nexus 4, I’m sure a lot of you are concerned how the battery life will fare. Well, early results aren’t very good. Based on recent unbiased and fairly scientific test results from AnandTech, the battery life on one of the most anticipated devices this fall will leave something to be desired.
I've seen lots of battery life forums, and most of them show great battery life (over 12 hours) with lots of screen time. I'm not even in an LTE area, but I get very good signal. My screen brightness is at about 30% and I have two e-mail accounts (Exchange push and Gmail sync).
