Galaxy S5 OTA Update Killed Battery Life
I installed the latest OTA update for my Galaxy S5 3 days ago. And now, since then my batter life has been horrible. I used to have roughly 40-60% battery life left after getting home from work, now it's about 18%. Please fix this. The same thing happened to my Galaxy S2. Battery life went to crap after an OTA update.
Is it possible to unintall this update?
