IPP 11 13.3 PR
Battery: Aside from video draining the battery faster than expected, now Safari seems to be doing the same.
Woke this morning and over breakfast, spent the next 90 minutes reading different articles and documents via Safari. No video. Sites have minimal advertising. Yet my IPP burned through 18% (at 82%) in that 90 minutes. When I do a breakdown in Battery for that time it shows:
Screen On 92 min Screen Off 0 min
Safari 79 min
Gmail 1 min
Messages 1 min
Gboard 57 min background activity
Home and Lockscreen 1 min
This might sound crazy, but in the last day and a half or so, I'm suddenly seeing much more normal battery drain on my 11" iPad Pro.
I did a DFU restore to 13.3 on Sunday morning and did NOT restore from a backup afterwards. This didn't seem to fix anything and then over the next day or two it just started creeping back to being just as bad as where it was pre-Sunday. For example, I think it was on Tuesday when my battery dropped 10% in standby over less than 4 hours. That same night, I just used the iPad until it drained completely and shut itself off, and then stuck it on the charger overnight.
Since that charge, things have changed. For example--yesterday after work at 5 pm, the battery was at 89%. It sat on my desk in standby until about 9 pm and was still at 89% when I started using it again. I used it from 9 pm until 12 midnight and the battery was down to 70% when I put it away. After 6 hours of standby this morning it had only drained 3%.
So I figure one of five things is going on now:
1) My new install from the DFU restore is finally just settling in and not chugging through battery anymore.
2) There was a rogue app causing this that was somehow not being reported in the battery use stats, and a recent app update fixed it.
3) Apple fixed something server side with iCloud that didn't require an iOS update. (There have been theories floating around that iCloud sync is the culprit on the battery drain issues some people have been seeing.)
4) I have just been doing a magic combination of things on my iPad over the last couple of days that have not exacerbated the issue, so it's still probably there but not being annoying right now.
or
5) My total battery drain until shutoff the other night actually did something. That's never seemed to make a difference before, but who knows.
I think #1 and 5 are probably the most plausible. 2, 3, and 4 are probably less likely, but plausible.
