The latest Samsung Galaxy Note 2 update brought a fix for the Exynos security update, but it is also causing battery life problems for users.
SamMobile reports the N7100XXDLL7 Galaxy Note 2 update for international devices causes battery drain, “much faster than previous firmwares.”
Galaxy Note 2 users are reporting bad battery life after the update, with reports of battery drain cutting usability by an hour to an hour and a half of screen time. Another user reports an overall drop in usable time by 12 hours. Individual user reports are listed below.
yes. Before update – 7,5 hours of screen work, now – 6,5 – 7 hours.
Not really, around 5-10% worse battery, but nothing massive
before update screen time on 8h Now : 6h30.
yep battery now only lasts max of 24hrs , used to get 36+ , MediaScannerService seems to be the culprit
While it is tempting to hold off for a future update, to get better battery life, this update is also supposed to fix the Sudden Death issue that caused some new Galaxy devices to randomly stop working. If the only issue was the Exynos security hole it would be easy to tell users it is worth waiting, but with the potential to wake up to a bricked galaxy Note 2, we suggest performing the upgrade and being vigilant about charging.
SamMobile believes Galaxy Note 2 users will see an update to fix the battery life drain before the Galaxy Note 2 Android 4.2 Jelly Bean update arrives.
It’s not clear if the T-Mobile Galaxy Note 2 update issued yesterday also affects battery life in a similar manner. The T889UVALL4 Galaxy Note 2 update for T-Mobile is available over the air or via Kies.
Stay tuned for more details on when the Galaxy Note 2 Android 4.2 update could arrive and potentially fix the battery drain issues.
