Samsung Galaxy Note 2 N7100XXDLL7 Software Update Based On Android 4.1.2 Jelly Bean Causes Battery Drain [Report]

The report has come from SamMobile saying that owners of the international variant of the Samsung Galaxy Note 2, running on the new Android 4.1.2 Jelly Bean, have been facing battery drain issue on their devices. The site has also tested the new firmware and has confirmed the same.

“We of SamMobile have also tested the new firmware and we can confirm that the new update indeed drains the battery much faster than previous firmware,” the report stated.

The new N7100XXDLL7 software update brought fixes for bugs such as the infamous Exynos vulnerability, the “Sudden Death” issue and the resetcode bug. However, as reported by a number of users, the update also brings battery drain reducing usability of the device by almost an hour-and-a-half.

Below are some of the responses from affected device owners, as mentioned by SamMobile:

- Before update screen time on 8h. Now: 6h30

- Absolutely it’s very noticeable

- Not really, around 5-10% worse battery, but nothing massive.

- I think battery drains fastly than 4.1.1 update. But now Exynos Xploit is solved.

- Not battery drain but 4.1.1 was way better than latest firmwares

- Yep, battery now only lasts max of 24hrs, used to get 36+ , MediaScannerService seems to be the culprit

For those users, who are yet to install the software update on their Galaxy Note 2, should they continue holding off anticipating another future update?

According to GottaBeMobile, since the software update fixes both the “Sudden Death” issue and the Exynos security hole, users can go for the update while being vigilant about charging just to avoid “the potential to wake up to a bricked Galaxy Note 2.”

SamMobile said although Samsung was yet to comment on the issue, a new software update based on Android 4.1.2 Jelly Bean could be expected to fix the battery drain bug before the newer Android 4.2.1 or 4.2.2 firmware.

Reportedly, Samsung started rolling out a similar software update (T889UVALL4) for the T-Mobile variant of the Galaxy Note 2 Wednesday, bringing the fix to the Exynos security exploit. However, it’s not yet clear if the update affects the battery life in a similar manner on the device.
