HATE my battery life HELP

[TabGuy]

i am down to 76% and this is the graph it shows

Something is definately amiss. After 4 hours, 8 minutes on battery I'm at 78%. I have Wifi and GPS on. It's not that it's sitting idle either, Bejeweled has used 9% of my battery usage.

Here's a technique I learned a long time ago on my Thunderbolt. And it works but requires REAL discipline on your part. If you're willing to do it you will have great battery life. It always works.

The premise is that you have an app eating your battery but none of the tools available tell you what's doing it. This uses the Scientific Method to determine the problem. The Scientific Method means you hold all variables constant except one.

Step 1: This is the painful part. Do a factory reset. Do NOT let Android sync your phone. It's a checkmark you'll have to turn off during setup.

Step 2. Do NOT, I repeat, do not install any apps. Period. Go at least a full day before you install any apps. This is the most important step.

Step 3. Measure your battery usage. More than one day is best. You will almost certainly find that battery usage is acceptable. If it's not, do not go to the next step until you've tweaked it enough by shutting off services like LTE or Bluetooth, etc. for satisfactory battery life. Make sure you have a full day of satisfactory battery life before going to step 4.

Step 4. Install 1 app of your choice. But ONLY 1. Do this at the beginning of the day.

Step 5. This is where the discipline and will power comes into play. Go an entire day to determine if that app is eating battery.

Step 6. If step 5 was successful and your battery is fine then go back to step 4 and install another app.

Step 7. If step 5 wasn't successful you've found a battery eating candidate. Remove it. Go a full day to make sure battery is back to normal. Do not install the battery eating app ever again. Period. Then to back to Step 4.


Using this method you'll protect your battery as much as possible.

I found out using this method that when I installed Shazam my battery usage skyrocketed. I can't prove it was Shazam but removing it returned battery usage to normal. It's possible that it was a combination of Shazam and another app so I couldn't be sure that Shazam was the culprit. But I would never have suspected Shazam via any other method.

Good luck. Managing a battery on a smart phone can be a challenge. But it can be done.

Dude, you have too much time on your hands. I could never go through anything like that (although it is very commendably scientific). I'd go with the fact that other than the screen the thing that does battery are the radios, and go from there. This phone will ID the apps using juice too, which makes it way easier. I used an app called Skydroid recently (it gives distances on golf courses), and after the round it said the % of battery it used (very little, because I went to the homescreen after I got the distance). I think the OP may just need to chill out and let the thing stabilize. The autobrightness screen setting is good too.
