Hello there,
I am currently writing a review for the Samsung Galaxy Note 4. The site I work with focuses on longer term reviews (90 days or more) and the ability of technology products to match lifestyles; we focus on real world use, not features and specs.
In the case of the Note 4, we have been reviewing two variants of the device, an AT&T variant and one through T-Mobile.
During the review process, we noticed that the battery life, with around 2 hours of on screen time per day, varied between 6-9 hours. Device encryption was not turned on during this time. This was similar between the two variants.
We recently upgraded our AT&T device to Lollipop. After the upgrade, our battery life diminished by over an hour, down to around an average of 5-8 hours, with still around 2 hours of on screen time. We also noticed significant stuttering in the UI, which was surprising, since the new ART runtime is supposed to be faster. We then turned on device encryption...ouch.
After turning on encryption, we have been getting around 8-9 hours of battery life, but with only an average of 15 minutes of on screen time. In addition, the security storage (com.sec.Android.providers.security) process routinely spikes up, with the entire CPU being maxed out for hours at a time.
At this point, our review for the Note 4, and indirectly Lollipop, will not be great.
That said, we really want to give the Note 4, and Android in general, a fair shake. As such, we are reaching out to experienced Android users to get worthwhile suggestions on what we might do to address the battery life issues.
Here are some pertinent facts:
-We have a 64 GB micro SD in the slot.
-The device has 2.7 GB of free space.
-Our network signal ranges from 3-5 bars most of the day, with some spots that we frequent down to two bars.
Please see the forthcoming screenshots for more details. (The Android central app denied the ability to attach a screenshot).
This request will also be posted on XDA developers for a broader audience.
We are trying to be as impartial as possible, so your help is appreciated.
Best regards,
Eric
