Increase battery life by 50%

I simply switched off location services and my battery life has gone up by ~50%.
I was really surprised that the location services took this much energy. I usually have Wifi off except when at home (if that's important) I haven't really missed the lack of location services - I just remember to re-enable it before running "Places" or similar

I'll try it, thanks.
I'm overseas on holiday and have had no data for 2 days (no wifi no mobile data). The battery hardly drained (%30). I was playing games and texting so I am now convinced that it is data and voice calls that drain battery.

How you switched off location services ?

I want to know how you turn off that as well thanks!

I'm guessing menu>settings>location and security> switch off wifi location and GPS location

Yes - that's all I've done.

Yes, all options is turn off.
My battery:
1d 1h 56min on battery
and now battery level is 38%.
Is the result same with you?

I'm getting ~10% drop over 10 hours when the phone is idle overnight. Obviously battery usage increases with calls etc. to 26% over 10 hours with some light calls and 3G based app updates. (no Wifi)

Increase battery life 10000% by turning phone off and removing battery
Number picked at random, YMMV.

I've tried this. Phone doesn't work

I turn on "Use only 2G networks" (in Settings --> Wireless & networks --> Mobile networks) and the battery life is incredibly increased ^^.
In addition, I also turn off the "Data enabled", whenever I need to access the 3G networks, I just turn them on again.

Seriously though, rather than trying to eke out every last milliamp of power from their batteries, i wish people would just buy a spare one and use that instead.

Gingerbread EXTREMELY poor battery life!

I keep reading about this new improved battery life with Gingerbread, however I've found the opposite.
By the time I leave off work, my battery is typically at about 84%, that's with no usage all day. Today is the first time at work I've been running Gingerbread, I'm only half way through the day and my battery is already at 69%, if it keeps draining at this rate, it's going to be down to about 30-40% by the time I've left off!

Did you do a factory reset ? It helped me a lot, i'm at 4 days 6 hours with 16% battery remaining.
Also check if you aren't scanning for wifi 24/7.

Have you checked what application is draining the battery?

Google
I had dreadful battery life and discovered that Latitude was polling constantly and also Google Talk.
Make sure you sign out of both and see if it makes a difference.

... and disable "Tell HTC" service, it'll help as well.

Disable? with force close?

Right, I've disabled Tell HTC, signed out of Google Talk and made sure it doesn't sign in automatically. I've also signed out of Latitude.
The top four things listed on the battery usage are:
- Display = 34%
- Wi-Fi = 15%
- Android System = 13%
- Dialer = 13%
All others are pretty much under 10%.
I'd rather avoid doing a factory reset due to the amount of information and length of time it's taken me to get everything set up. However, I made the mistake of thinking that Wifi wouldn't be used if mobile network was on. My plan was that I would then connect straight away to Wifi when I was at home, and when it lost the signal it would switch to my mobile network. Well, this seems to work fine, however obviously as shown above, it's still using a fair bit of battery. I think I'll just start turned Wifi off completely until I'm going to use it.

For enabling/disabling wifi i use https://market.android.com/details?id=com.sas.inappwifitoggle . Long press search key and it gets enabled or disabled.

- Display = 44%
- Wi-Fi = 15%
- Android System = 23%
- Dialer = 23%

I use greenpower realy great app I'm running Gingerbread and I'm getting nearly 2days out of my DHD

Cool, looks like a handy program to have!

Check out this thread about the Dialer issue:
http://forum.xda-developers.com/showthread.php?t=1069251

My battery life hasn't improved either.
With moderate to heavy use I get about 6-7 hours only. My brightness is usually set at 30%
Display - 69%
Dialer - 8%
Cell standby and others - 4% and less
Is this normal?

Could you give us some more information here ? I mean what type of system are you using, Stock, or some type of ROM ?

I'm running LeeDroid's latest ROM, 2.3.3 and have Green Power installed so data gets turned off when my screen is off.
Auto-sync is turned off too.
In regards to mail, twitter syncing I set mine to every 6 - 12 hours.

I have had gingerbread RUU for 1 week now. With Froyo I used to get 15-30 hours depnding on wether I used 3g or Wifi(Wifi more conservative of battery). Since GB update my maximum battery lasts for 12 hours. I have noticed severe battery drain uder WiFi. Previously with 2.2 with the phoned switched off at night with Wifi enabled, the battery would drain approx 7% in 7 hours. Well today I did the same test switched off phone,left wifi enabled and the battery dropped from 90% to 46% in 7 hours which equates to 7% an hour with the screen off!
This is unacceptable! I sent HTC an email to expalin this but all I got was list of ways to reduce battery life such as swich off wifi, move to 2g, switth off live wallpaper etc etc. But all of this is absolutely of no use if the battery is draining at 7% an hour with the screen off. As I mentioned before with 2.2 the wifi drainage was small approx 1% with screen off.
Can someone suggest a solution?
1)Should I contact HTC again?
2)Try a custom ROM?
I havent tried a custom rom yet as the phone has been runnning well minus poor battery but I may have to if a solution cannot be found.

I noticed the same drain as well when I updated, but after a few days of testing I found that the problem was with one of my apps widgets. My guess is that the app is not efficient on gingerbread.
After removing the widget, everything was fine again.
To sum it up, check your apps.

when you say check your apps what are you using to find out whats running what.
Also how do i know what i can stop without making other things crash on me
for example. i do not use my sense account so can I shut dwn all things to do with sense that are running without risk?

I had the issue with battery life too. Just get the wifi switch on your homepage and turn off if you're not using it. Otherwise it constantly scans and leaches your battery.

Battery tip for people with bad battery life.

I've had bad battery life since I bought this phone on release day. I would get no more than 1.5-2 hours screen on time. The battery wouldn't last more than 12 hours. I've been messing around with it since then but still had bad battery life up until the last few days. Now I get 3.5-4 hours screen on time and I'm a moderate user.
Here is what I did:
1. Go to Google maps and then go to settings and untick anything that is ticked then click on "location reporting" and set it to do not update your location.
2. Go into the phone settings>location services and untick everything. When you want to use maps just turn on gps.
3. Get the app "battery calibration". First charge your phone to 100% and keep the charger plugged in and then go to the app and Press calibrate. Then use your phone till the battery is dead (turns off) and plug the charger in and let it charge to 100% while it is off.
Turn it on and then use it till the battery is dead again and charge while off to 100%.
I'm not saying this is guaranteed to work for you but it has for me.

You know my problem is I did that and when on Jb lib battery drain like crazy.Back on ICS no problem with battery can you explain that why on ICS calibration is not needed ???

First two items I agree on. GPS uses up a lot of battery, though from personal experience, it didn't dent my battery too much anyway as long as I don't have running apps using it.
But the last point. I believe those battery calibrations are actually useless. There was some article from the android team describing why.

The 2nd and 3rd are completely useless.
People who use gps know that even if you tick those location services, it only gets enabled when an app requires gps. Thua, battery is only lost if you use loads of navigation services. Unchecking those won't do any good.
Battery Caliberation is just what you can call the perfect reading that is shown on your status bar. Ultimately, whether you caliberate or not, battery gets charged upto 100% only. It won't surely exceed that.

A better idea:
Disable auto sync for accounts
Disable GPS (and wifi gps)
Disable auto backup of Gmail account
Set wifi sleep policy to “when plugged in”
Disable motion
Check your apps settings and disable useless background sync​

Setup a static IP via your router.

I had issues with Chrome Sync - when enabled it prevented phone from going into deep sleep. So if you use Chrome and struggle with battery life this is one more thing to look at ...

Official Facebook app uses a lot of power and waking device for many times. Use browser for facebook or alternatives...You will see the diference !

good list id like to add:
freeze unused apps/battery hogs if used sparringly (with titanium backup)
set wifi to always on, switch off manually when not in use
firewall apps that dont require internet

I agree on the Facebook app. I will charge my phone to full, reboot it, and then let it sit overnight without using any apps and it will be one of my top processes in better battery stats. I really like using facebook simply for the picture and phone number syncing. I guess I could always go back to haxsync. On my Galaxy Nexus since I can't use facebook app to sync I just use mobile page and it definitely is better on battery life.
I've been trying to improve my battery life on 4.1.1 LIB as if I leave it on Wifi overnight with no use after reboot and full charge I'll see Deep Sleep at maybe 90% if I'm lucky. I'm losing almost a full hour of sleep time over the course of 7-8 hours. I think Facebook is part of it, also it seems to be worse when I use the S3's built in alarms.

Go into Settings -> Location and disable everything? You mean that we should disable:
1) Use wireless networks (location determined by wi-fi and/or mobile networks). I really don't see how this saves battery.
2) Use GPS satellites. This uses up battery ONLY when an app requires GPS (and when the icon shows).
3) Use sensor aiding. See above.
4) Location and Google Search. (only used to get your location when you're connected to GPS and/or wifi/mobile network).
I really don't see how this saves battery.
On a side note, one might want to freeze unwanted apps, not use too many live wallpapers, sync only when needed, and get rid of unwanted widgets. THAT might help.

Better tip. Use your phone with everything turned on as it was designed like I do and get 4 hours + screen on time, and 1 to 2 days useage depending on how much it's used.. simples...

I really don't see the point of buying a phone like this and turning everything off!
Google now won't work properly with all the location stuff switched off.
I always get through the day with everything turned on, in use power saving at work and switch off wifi that's it.
If the battery runs down have a back up waiting, galaxy s3 owners are always going on about it being good that our phone has a removable battery and iphone doesn't but there are still many people not happy that their battery runs down quick!

The best thing I ever spent on for this phone was the official samsung battery kit. At least I don't have to worry about the battery at all and I can leave all the features on.

Yes that's true but this is not for everyone. I don't use Google now and why should I use wireless networks when there is a built in GPS.

Thank you OP. That was the problem with my phone. Now its awake when the screen is on. Before that, it was awake every 5 minutes. !!!!

And after you've turned every single feature off, you can stand back and admire your Nokia 3310

You're only turning of location services. Why does the phone need to know where you are 24/7? Just turn it on when you need to use maps or location. Not hard.
My car was designed to be driven, does that mean it should be left on while I'm not using it? Think about that.

Battery Drain

I've read through this thread (http://forum.xda-developers.com/showthread.php?t=2385843&highlight=battery+drain) but did not find a solution. A little about my device: it is not rooted and is completely stock. I did not have battery drain issues when I was on 4.2.2, but ever since I updated to 4.3, I've experience this issue. I would lose about 20 - 25% battery life through the night. When I wake up, it would be around 75-80% full.
I've looked at my battery stats and it seems as though Android OS is 19% and Google Services is at 17%. Prior to updating to 4.3, I would be able to toggle the GPS on and off simply by using the Power Widget, but after 4.3, I noticed when I toggle the GPS icon, it would take me to LOCATION ACCESS. As of right now, "Access to my location" is ON .. GPS satellites is UNchecked .. and Wi-Fi & Mobile network location is CHECKED. I tried to turn location access OFF last night and have everything unchecked, but it didn't seem to make any difference.
What's going on???

Feel for you bro. I have the same issue as well. It's like 4% drain per hour, only by Android os.

To decrease google services battery consuption you can delay the frequency of sync in the settings! But i give you an advice, flash a costum kernel like franco or matr1x and you will enjoy a lot of extra battery life

google now draining battery

I have used G2 for about a week, battery life has been superb, decided to turn on google now yesterday, drained my battery like 20% in 10 hours while I was sleeping it was keeping phone awake
I turned it completely off now. Does anyone use google now? Anyway to use it but not drain battery?

I use it. Idk how much it drains at night cause that's when I charge the g2. My battery does pretty well though and I'm on it a ton and it still lasts all day.
LG G2

Google Now will use some more battery because it's checking for updates and probing for location periodically, but nothing like you describe, so something else was going on.

go to google settings, location, and turn off location reporting and location history. Google Now will still work fine, but your battery will immensely improve.

OK great thanks going to give it a try, what about do I check off Access Location under that same menu or keep it off?

You can leave that on, it shouldnt impact your battery by itself.

Thanks one more question, under main settings -> Location access
Do I need any of these on (Access to my location)? and if so which ones? GPS & Verizon or Wi-fi & mobile network location. Right now I have all of it, not sure which is least battery drain

You only need GPS on if you need very accurate pinpointing, like using navigation, mobile network location is fine to leave on.

Another tip: Google Now>settings>Phone Search
You can change which apps Google Now searches on your phone. This sped up Google Now for me as well as helping with battery.
