[Q] Phone feature broken cell standby drains battery - Xperia Play Q&A, Help & Troubleshooting

Just picked up an old Play for gaming and the phone functionality is broken so I got it for cheap. The issue is the cell standby keeps draining the battery like I was only getting 3 hours with OC and gaming with cell standby taking up 25% of that. I can set it on airplane and that solves it but the WiFi goes on and off or sometimes doesn't come on.
Is there a build.prop edit I can do to make it think it has no phone hardware inside?
Thanks in advance,

[Q] Battery drain

Hi... I have an Xplay rooted on 2.3.4 and removed light bloatware, but still my battery drains fast...
I must charge phone every day and I dont use a lot of heavy gamming... I only play in bed at night and normaly to drain the rest of the battery before charging.
I almost never use 3G, but have always wifi turned on...
So, resuming, my battery only lasts about 12h-14h per day...
As you can see, in the attachemt I have 2 times the same thing (portuguese language, but will translate):
- Inactividade do telefone 28% (Inactivity off phone)*
- Wi-Fi 21%
- Telefone inactivo 15% (Phone inactivity)*
* This 2 things arent the same?
I have a few questions:
1º - I have read about people who can have phone about 2 or 3 days, others with 20h or more. What is the most accurate and normal on this phone?
2º - If wi-fi always turned on, will drain battery?
3º - Why most off % is used when phone is inactivity?
Sometimes the phone dont loose battery when "sleeping" (it take 2h to loose 1%), but other times, when sleeping, battery drains 10% or more in one hour. I have read about a bug in Android OS that drains battery when phone sleeping. Does this bug applys in ALL ANDROID phones, or only Samsung? Read it on here: http://forum.xda-developers.com/showthread.php?t=1290020
If I charge phone every day will get battery "addicted"?
One thing im shure: the 3 first itens on the screenshots are draining my battery whitout a reason (i can understand wi-fi, but can't understand why 2 things saying phone inactivity, uses 43% of battery)
In that screenshot, battery is on 60%, so I losted 40% in 6hours with 20 minutes of gaming... and on those 6 hours, almost half, phone was "sleeping", again, it shouldnt drain battery when sleeping.
Thanks in advance for your help
What's shown as draining your battery the most is your phone's cell standby (your 3G & 2G network, or 4G if you have it). The third on the list describes your phone when it's not in use (screen off). Don't worry about that one, a higher % only means your phone is often in standby.
Having Wi-Fi on will often use more battery than using your phone's own network. To save even more battery, turn off 3G connectivity when you're not using it (you will still receive calls, just no internet, but you use Wi-Fi anyway).
Charging your phone every day is perfectly fine, just make sure you unplug it once it hits 100%. If you leave it plugged in while it's fully charged, it gets bad for the battery after a while.
That article about the battery drain in standby is likely just for Samsung devices. What is likely draining your battery are apps and services that run in the background and use the internet while in standby.

95% of the time, 3G connection is OFF. I use Wi-fi connections, because I have many hotspots for it...
I don't have many APPs and the ones that I have installed (non-stock apps), dont run in background.
Today, I turned off wi-fi, and only turned on when need, and for more than 2 hours, only losted 1% of battery (have takken photos, and made phone calls only).
After this I used wi-fi for 20 minutes, and losted 8% off battery. So I think, Wi-fi is the problem. Please correct me if im wrong:
- If I have wi-fi always on, phone is always searching for wi-fi connections, even when sleeping, so battery drains much faster.
As you can see on the screenshot, with no wi-fi, for a little bit more than 2hours, only 1% of battery losted
Well you answered your question. Wifi is the problem. If it searches for wifi networks all of the time the battery will surely drain.
Definitely Wifi. It absolutely murders my battery when I forget to turn it off when I'm not using it.
Yes... for shure... its crazy like hell... lol... half an hour playing... half an hour surfing (youtube for my son... i put videos for him, once in a while)... and wi-fi drained more battery than gamming (FIFA 2010, Angry Birds, Spider-Man... also my son played)... funny thing, he has 20 months old, and love Xplay, more than me...
So... the hole day, I kept wi-fi turned off, and only turn it on, when needed... more than 12h latter, still have 62% off battery... and for the first time, will not charge this night...
Was so simple, as turning wi-fi off... check the screens...
Thanks all that helped

[Q] Is this unusual battery drain from the screen?

Hello everyone! I just switched to my first Android device and am truly enjoying the experience. I can't believe I was using an iPhone for so long. I finished draining my battery for the first time and recharged it and am draining it again. My phone indicates that the screen is consuming around 66-70% of the battery drainage while everything else is quite low such as the Android OS taking up about 12%. Is this typical and does it improve over time? Thank you for your help.
this is normal but seems like that is pretty heavy use. if your phone was barely used then that is not normal.
I am going to further diagnose this. I have my brightness set to auto. I wasn't really using the phone that much. I flashed it to the yakju build and it is running 4.0.2. Is there anything I should do to test the phone?
what is your screen on time
I'm looking at
9h 56m on bettery
Android OS 33%
Phone Idle 30%
Cell Standby 22%
Screen 9% (on time 9m)
Wifi 5%
Google Services 2%
This is after the phone being nearly untouched most of the day, no calls or texts and nothing being done but checking my email once not too long ago. It's on Auto-brightness which sucks because it appears to be on the darkest setting but without that my battery seems to go from full charge to 50% in 1-2hours with moderate usage (Browsing the web, Checking email, Browsing Market, few phone calls and texts) and it sucks that I feel like I cant play with the phone because it'll be dead when I need it and without Auto-brightness the battery dies even quicker.
Almost feel like I need to be tethered to the charger.

you either have really bad signal and/or 4g and/or a process keeping the phone awake, in your case the high cell standby time suggests the first two
This seems common for the lte version. The gsm version gets very good battery life especially idle drain. Turn off lte is your best option.

Assuming you have the screen on a lot then yes. Those big beautiful screens are hard on a battery.
If you're on the LTE version using 3G only you will get around 3 hours screen on time MAX.
GSM version you will probably get 3-4 hours screen on time per charge.

Battery Usage Question

Hello guys,
I would like to ask something about battery usage. I am not sure if it's related with alquez's Cyanogenmod 7 port or is it a normal behaviour but I just wanted to ask.
My battery info is:
1d 1h 50m 46s on battery. Current left battery level %54 (that's what cyanogenmod says)
Battery usage:
Display %54
Cell Standby %27
Phone Idle %15
Android OS %2
1-) My first question is, my screen brightness is almost %25 or maybe %20, auto brightness is off to save battery. But still how it can use %54 of battery? If I use auto brightness, then does it mean the battery will be drained less than in a day?
2-) Are those stats looking good? I am not quite sure if it's because of rom or because of android 2.3.7 that comes with rom or something else
3-) I don't use any connections at background except phone signal, I only use 2g connection when I want to use internet.
4-) As extra, this time I used FM radio on phone via bluetooth.
So here it is like, I enable the 2g connection or wifi, to check the updates for the phone like for 5 minutes. Then battery state goes from %69 to %61 almost less than in 5 minutes.
When the phone fully charged (checked from the battery settings), it stays %100 like till end of the day (when I unplug from charger at morning). But like in an hour, when I use it, it drops from %100 to %85 pretty fast.
I don't play any games on phone. Just using facebook, foursquare and market to update my apps.
So I am wondering if something is wrong with battery (it's the default battery, I really dont want to buy a bigger sized battery) or is it just rom's cause.
Welcome to your HTC Wildfire S!
this is pretty much normal and is nothing to do with your ROM.

Terrible Battery Life. How Do I Diagnose the cause?

I'm experiencing pathetic battery life on my 10, which is just about a month old. This is without me using 4G LTE at all. Only Wi-Fi + 3G.
- I'm seeing drain in the range of 10-15% an hour with light usage.
- SOT never goes beyond 3-3.5 hours.
- I've installed the GSAM Battery monitor app. But there's nothing out of the ordinary on the stats. Screen always seems to consume about 30% of the battery. Rest is small bits from multiple apps.
I'm going to have to do a factory reset to fix this. But I really don't want to.
Is there any other fix?

For me 3 - 3.5hrs SOT was normal on stock. Check settings/location/scanning and turn off wifi scanning that has been known to drain battery
+1 on the wifi scan. That will ghost your battery. I turn off vibration feedback as well along with restricting location permission on most of apps so my phone isn't constantly looking for itself on gps which will also drain battey
Disable FB notifications, wireless and BT scan, wireless notifications and optimalization . Set wifi to never when screen is off

Battery life is subjective.
It'll depend on what you have running, what you restored, the apps and their state, your phone settings, brightness etc. What's connected and what you are doing on your phone..
HTC hasn't historically been the go to phone for great battery life.
A few hours 3-4 SOT is pretty decent for a phone.
You could do the normal things like, switching off connectivity options when not in use, ie location, wifi, data, NFC.
Check what apps are running, for example if Google photos is backing up your pics it's going to hit battery life.. Other apps will do the same, Facebook etc.
I'm not saying don't use your phone but depending on your habits you'll have varying degrees of stamina from your battery.
First thing to do, lighten the load, then grab better battery stats and see if anything is keeping it awake.
i suspect my router here and dhcp lease to be an issue, battery issue happens every dhcp lease (24hrs = 86400) when phone wifi does not turn off wifi after 15 minutes. static ip does not help at all, only rebooting wireless process on router. other than that battery life seems ok - 48 hrs light use.

Battery drain issues..

Hi , i got a note 4 from rogers for now 2 years. My old battery was dead so i bought a new battery. I got a lexmar 3400 mah from best buy.
But i still got battery drain. Nothing was done today on the cell phone except. Sms, some internet search and 1 hour of songza music.
And im about 28% left for 3.5 hour of use...
Is the battery truly 3400mah? The only 3rd party battery that's trustworthy is anker so I'd start by seeing if the battery is legit before going further
Wifi is possessed, battery drain
My wifi is going crazy ! When I try to turn off the wifi it keeps turning it back off and on again. It can stay on with no problem. Because it keeps turn on and off its killing my battery life, anyone else experience this or better yet found a fix ?
