After 2 weeks of tests, I found these problems in T62’s battery life.:
Quote:
1#battery life’s info is not accurate and has some errors (I think (+3%) to (-3%) is added to the battery life).
2# Wi-Fi drains the battery. I transferred 350mb of files via Wifi from my pc to t62 (kept wifi ON for 40min) and lost 15% of T62’s battery life before doing the battery test.
3# battery drains much faster after two days. Many reviews stated this problem.

Battery test: (the device was in sleep mode 98% of the time)
9/12 charged my device 100% in the morning + 30min of reading
9/13 100%. No changes !!! Sleeping mode
9/14 (97% to 87% sleeping mode) problem #3 started. Rebooted my device.
9/15 (87% to 70%) problem #2. I downloaded and tested few apps.
9/16 (70% to 65% sleeping mode).
9/17 (65% to 50% sleeping mode). Problem #3 again. Rebooted my device
9/18 (50% to 39% sleeping mode). Rebooted my device.
9/19 (39% to 30% sleeping mode).
Average discharge rate:
1% each 3-4h (sleep mode)
Problem 1&3 (1% in 2min)
I think my device's battery will reach 0% after 2.5 days (the total: 10 days in sleep mode)
Although, I found a way to reduce battery drain (problem #3) by using auto reboot app (each 24h), I could not find a way to solve other battery drain problems. From my point of view, the cause of these problems is the software (android build & kernel build) because many people reported a bigger problem in battery life before the latest update.
BOYUE & Icarus's OS developers have to fix these problems
