[One (M7) General] yvibes:
Ok firstly, just to make it clear I know everyone has their own way in which they use their phone so you may not get a lot of battery life out of your phone. However I have achieved 7 hours screen on time for the past 2 days while actually using the phone how I normally would!

I know there are already 2 threads about battery life, I decided to create this thread so that everyone who is doubting me and everyone who wants to know how I did it or what I do with the phone can look here for all the answers. I have found myself repeating posts over and over again.

I have had my phone for more than a week now so its gone through its fair share of charge cycles now so make your judgement about battery after the first week or so.

OK here are my screenshots for the first day I got 7 hours screen on time!

Here I will tell you what I did on that day, all the settings etc etc:

[] I browsed facebook, twitter, instagram and the web.

[] A couple hundred messages sent on facebook, whatsapp and through the text messaging app.

[] Took some pictures and posted them on instagram, also took a couple zoes

[] Wacthed quite a lot of youtube videos

[] Downloaded many apps

[] Had a couple attempts on temple run 2, real racing 3, vector and logo quiz

[] Used the remote through the ir blaster

[] Used zedge to go through many different notification sounds to download the best ones

[] Made a couple phone calls

[] Spent insane amount of time on xda premium app xD

[] Turned on auto sync for 10 minutes every couple of hours, turned it off once everything synced (two gmail accounts, email, facebook, twitter, weather, dropbox, google and whatsapp)

[] Used 3g for 2-3 minutes, most of the day on wifi

[] Most of the day was on 3 bars of signal or more

[] Lowest brightness for most of the day, set to 15% while showing someone pictures for about 20 minutes

[] POWER SAVER MODE TURNED ON AT 30%

Bluetooth OFF, gps OFF, nfc OFF, airplanemode OFF, blinkfeed OFF, google now OFF

Here are my screenshots for the seccond day I got 7 hours screen on time!

Here I will tell you what I did on that day, all the settings etc etc:

Pretty much same usage as above, however....

[] I did have a sports notifications app running in the background during the last 10% of the phones battery. This app was sending me notifications in real time about football matches going on.

[] I turned power saver mode on at 20%

NOTE: THE 9-10 HOUR GAP IN THE SECOND SCREEN IS WHEN I WAS SLEEPING AND THE PHONE WAS IN AIRPLANE MODE! THE PHONE DRAINED 3% BATTERY IN THESE 10 HOURS.

Here are my screenshots for my 3rd day (where I almost got 7 hours again, I'll explain below why I didnt make it this time)

As you can see on my 3rd day I got 6hrs 30 mins screen on time which is still insane!! But my usage was slightly different.

[] I spent half the day on 3g and the other half on wifi

[] I was in an area with 2-3 bars of signal most of the time

[] I watched more youtube videos than the other two days

[] Also downloaded and tried out many different games (A LOT)

Thats all I did different and I still almost managed the 7 hours! Just half an hour shy :(

Extra things that you should know about

1) As you can see from my screenshots for both days my device hasn't stayed awake (due to wake locks etc) for long, less than 30 mins. Some people know that I was having battery drain issues from 'mediaserver wakelock'. At one point I had 900 wakelocks even though I didn't play any media :/ this thread solved the issue for me.

I downloaded the tool which scanned my music folder and identified me about my corrupt mp3 files which I then deleted. Basically, after listening to music with these corrupt mp3 files in my library, the mediaserver would go in a loop causing the device to stay awake and have many wakelocks. After deleting these mp3s, mediaserver is always near the bottom on the app sucker page in GSAM battery monitor app :D

2) Funnily enough, as soon as I decide to turn off blinkfeed... I get 7 hours screen on time XD so blinkfeed must be a battery drainer. I'm going to set up blinkfeed again soon to see if my results change and if my battery life is affected by it. (Just setup blinkfeed and seeing if it actually affects the battery life I'm getting, CHECK HERE SOON FOR UPDATE ON THIS)

To disable blinkfeed, just go into topics and services and just de select everything. Then just set the normal screen to the right as your default home screen.

3) The phone comes preloaded with some apps that you may not use. I found that some of these apps were always running in the background even when I'm not using them. You can't uninstall them which is annoying but you can disable them if you want. Just go into settings/apps/all then just click on the app you want to disable (YOU CANT DISABLE HTC APPS) then just click disable. I did this with the play books, magazines, 7 digital, sound hound and a couple others I never use.

4) Disable Google now. If you like Google now, like the functionality of it and use it regularly then you don't have to do this. However, from personal experience and testing, I have found that my battery life increases a lot if I have Google now disabled. Google now is definitely a great app, if only they figure out a way to drain less of my battery then I'll enable it again.

5) You will find this in most places telling you about battery life but.... Turn off things you don't need or aren't using. When your done with Wifi, switch it off. When your done with mobile data, switch it off. Bluetooth, GPS etc etc. This will save your battery, if you have everything turned on for no reason then don't complain about bad battery life.

THIS IS ALL DONE WITHOUT USING ANY APPS TO SAVE BATTERY LIFE. SO NO JUICE DEFENDER OR ANYTHING LIKE THAT :P
