Fresh battery not really fresh
Got fresh iPhone4S battery from iFixit, no big deal to put it in. Although at first it seemed to sustain the unit for a couple days, now it barely lasts a one day, doing the common drop quickly to 20% then prematurely die. Silly thing does a lot of surfing by itself, 'Siri' or other apps inquiring about things in the background, despite all services being off. The decline may have coincided with iOS upgrades, the way Apple tends to ruin everything. Now at 9.3.5. Anybody have any suggestions?
Is this a good question?
