Random decreases in performance

[Chris Connelly]

Has anyone noticed random decreases in performance with their phones?

Yesterday, I left for work with a full charge, and seemingly fine performance. Once I got to work though, I noticed whenever I used my phone, there was a lot of lag and studdering, it was running particularly warm, and my battery was draining much faster than it normally does.

So I closed all programs, tried switching between both wifi and 4G to see if there was a difference (there wasn't), and monitored my battery usage for anything odd.

By the end of my 9 hour shift, I was at around 35% battery life with around 2 hours of SOT (I usually leave work with around 70% battery life and maybe an hour and a half of SOT).

The only noticeable difference in my usage stats was that it showed the Facebook app had used the largest percentage of my battery when it's normally number 3 or 4 on the list.

Now I know what you're thinking, it's the Facebook app acting up, but I've only had the problem and really random and isolated times, and I use the Facebook app constantly, which makes me suspect it's maybe a network issue or some other kind of internal issue.

Any ideas?

What's the cell signal like at work? If it's poor, then that can cause battery drain and heating.

You can also try booting into Safe Mode when you're experiencing the sluggishness, which can help narrow it down to something you installed vs the system itself. https://support.t-mobile.com/docs/DOC-28008. Or you can wipe the cache partition: https://support.t-mobile.com/docs/DOC-30240

There was a day a week or 2 ago when there was apparently an issue with FB servers. There's another thread where this was discussed. My phone also saw a large battery drain that particular day. Haven't seen that since.

I suspected it was the cell signal, but it's usually okay at work.

It would probably make more sense that Facebook had some of network-taxing flub up like before.

Although I will definitely be trying booting into safe mode if it happens again.

Try installing GSam so you can review the cell signal strength graph over a day in the office. You might be surprised -- maybe there are some parts of the office that are black holes!
