2g/3g/data/no data battery life TEST

Here are my test results. These are not benchmarks or controlled environment tests. They were done simply to give an idea of real life battery life.
2g no data

The massive drop is due to a phone shut down (reason unknown)
3g no data
2g with data
3g with data
The workings were simple: set the desired network (2g/3g) and select data active/inactive, charge to 100% and use normally until 20%. No apps for battery savings were used. With the data active tests i had gmail and facebook sync. (although these were active in both 2g/3g with data tests i was more inclined to check facebook during the 3g part because it loaded faster)
Tests were done using
Rom : ParanoidAndroid Build 7
Kernel : Harsh 2107
BB/RIL : 725/622
I will post another test with 2g vs. 3g using battery 2x (app i use to save battery)

In the next test please post a screenshot showing Screen on time =D

Hmmm
Looks good...but i think you used your phone in 4 days only few ours to get this,right?

i used it as often as i needed it but the data being inactive it was used only as a phone (as the old nokia 3310) for calls and text (and the ocasional picture). I think it's a good indication that smartphones do not have bad batteries but the fact that they are used as a smartphones gives them the bad autonomy (see test 4)

But nobody want a Smartphone (dualcore) to use it as a 90s cellphone.
My O2X in 2G with data just work for 12hrs in a normal job day (i´m a doctor using a lot of medical apps, making and receiving several phonecalls, 30mins of GPS, whatsapp texting and taking an average of 10 pictures/day). Not using battery saving apps.

[Q] Terrible Battery Life of I-9295

Hi there, I have been struggling from terrible battery life for a long time. Even calibration didn't make any changes. So today I bought a brand new battery and calibrated it but it didn't work very well.
Here are the statistics:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Anyone can help?

Don't believe in battery calibration. It's a hoax. When turning on all lights and power consumers at home 24/7 the power bill usually get large numbers.
Focus on active/running apps and features you seldom or never use. They are sucking the battery and keeping the phone awake.
Ask your self - do I need GPS, WiFi, Bluetooth on always, Email check inbox each 15min, Calendar and background sync, Social forum updates Tw** Fa** Sna** anytime?
Enable when YOU need them, else off.
Android KitKat 4.4.x allow you to deactivate many apps without un-install.
This category of apps is usually called bloatware - the ones Samsung decided you must have but never use.

Thanks for your reply. But, I have even bought Greenify and I rarely use those battery-draining features of the phone.

Mine's been doing that for a while now too. It's always 'Android OS' and 'Android System' taking the top 2 spots in the battery stats. I've just gotten used to always keeping it on the charger.

Google Play Services battery drain

I assume that others are having this issue, and wondering if there is some fix I may be missing short of turning off location services (find them helpful and don't feel I should have to cripple my device for battery savings). I believe it is linked to it using WiFi networks to search for my location, although my WiFi is toggled off. This across all ROMs I have tried, though randomly it doesnt happen but always returns.
Thought it would be helpful to have a place to have open discussion on this issue and see others impressions.
Thoughts, suggestions, fixes?

1. Settings > WiFi > Advanced > WiFi Scanning Always Available (disable)
2. Settings > Location > Google Location Reporting > Off,off
3. Use App Ops (built into roms known as "Privacy Guard") and go to Google Play Services and deny permission to Keep Awake (Read more, http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525 )

Why thank you!! I have done this, and will see how it goes. GPS wasn't in privacy guard within SlimLP but accessed it from settings>apps>all>google play services>permissions>modify

When you go into Privacy Guard, go to Menu (top right) and enable Show Built-in apps or something similar to that. Then you'll see GPS in Privacy Guard

Indeed!! Thanks boss [emoji106]

How do I do this with stock 5.0.1 / rooted

I really hate to bring this thread back to life and I apologize for that but I'm suffering from this bug and it's nasty. I'm barely getting 2h of SoT while other dudes are getting 3~5h of SoT. I did what this thread said and after tweaking with app ops freaking Google Play Services is going nuts crashing every 2 seconds, sometimes one right after another with that annoying message making the phone unusable. I'm on Pure Nexus 5.1.1, no CPU tweaks nor kernel mods. As far as I go with battery related apps/tweaks is greenify. Any ideas?

Did you make a backup before applying any changes in privacy guard? Have you reverted the changes you made back to the default? Also, try going to settings - applications and clearing data for Google play services

Battery Saver mode in Android 9

I can't seem to find the Battery Saver mode in Android 9 (MIUI v10.1.2.0) anymore.
There's also no indication in the battery meter for activating such mode. (used to show as orange in the meter background)
Am i the only one missing this?

Whatsapp / Line notifications have always been unreliable in Chinese ROM, that is quite a common issue.
Another thing that you might check is under Settings -> Battery & Performance -> Scenes -> Non-interactive mode and make sure it is DISABLED.

Internet cuts for some apps randomly

Hi everyone
I have a weird problem, when I'm using my phone and let's say on Instagram sometimes when i refresh the feed it's just doesn't.. i doesn't say you don't have internet connection it just won't load the new posts and keeps the loading indicator rotating
Another app is Spotify when it's randomly playing songs that haven't being played before (not cached) it's stops suddenly of loading the next song and resumes after a couple of minutes
Same problem with tinder not loading the incoming messages
Only can be solved by disconnecting and reconnecting WIFI or using cellular data
My phone is fully stock with the least official update
I've checked:
Background restrictions.
When Spotify or Instagram stuck I swhich to another app say YouTube and it's perfectly working and loading, going back to Instagram and it's still stuck and not loading.
WiFi router is not far away from me so the Signal is strong.
Do you have any idea how can I solve this without resetting the phone ?
Thanks

Did it start with csd1 update?

Thanks for the reply
I actually don't remember but here's the version I'm on now
Current version: N960FXXS2CSBA/N960FOXM2CSA2/N960FXXU2CRLT

Having same issue. One UI. Has been an issue since latest update.

In Android Pie v9.0 in app settings you can turn off battery optimization and it should prevent the app from being put to sleep. Maybe this may help. Or if wifi data saver is turned on this can cause issues also. There is one other menu/screen that allows you to change settings of when/why/which apps and how they are controlled by Android to save power and allows apps to be put to sleep after a certain amount of app unused time, or when it predicts that you are not normally using a particular app at a particular time. I cant seem to recall where I saw it or how I got to it but if I track it down I'll be sure to post the info because I think it may be a likely cause or fix for your issue. Only other thing I could figure it could be the modem firmware that your on is buggy and hopefully it will be fixed in a future update.

Here is what I was looking for. You go to settings>device care>tap on battery>tap three dots top right>tap settings. In there is some stuff that may help with your issue.

Thanks for the reply, I've actually already done that I've disabled all the settings related with putting apps to sleep at device care/battery which doesn't solve the issue
Yet i still have to try un-optimizing the apps surly this would lead to battery drain but let's see what happens.
I'll keep you updated with the results

So I have disabled all of power efficiency related settings in device care/battery section
And also disabled doze optimization for the effected
İ can say it's a lot better now but the issue still occurs
