Galaxy Note 2 Update N7100XXDLL7 Causing Battery Life Problems



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.

Galaxy Note 2 Battery Life

The latest Galaxy Note 2 security update cuts battery life on the phablet.

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.

    Well I found it to be better in fact but the only way to really find out is to do controlled tests which blogs or mags should take on as part of their mission.

    I am new to the Note and my husband just made a comment about how quickly his battery drains. I thought it was just me! What is the solution?

    My galaxy note 2 seems fine on battery life but I have experienced 3 occasions where the phone had just gone dead and I have had to take the battery out to re-set it. Hope the update fixes the problem

    T-Mobile GN2 and my battery life plummeted. I normally have 40-60% battery life at the end of the day. Now I am down to 10-15% at the end of the day. I have had my phone off the charger with limited use for 3 hours this morning and it is already down to 85%.
