Losing battery at about 8-10% every hour on idle - Epic 4G General

Hey everyone,
My phone was doing great with the battery life until recently. It might have been some app that got an update that effed me up, but not using my phone all day, I lose battery real fast.
Not sure what's going on, but it's dying real fast!
Any ideas or help?

My phone did that from day one practically. I honestly thought it was expected. Later I scrapped all of my apps and reformatted basically. That's when my battery life became amazing. I'd suggest checking all apps for excessive syncing issues. I am pretty sure my culprit was Yahoo Mail. I've since switched to GMail with a bookmark to yahoo if I need to check it.
Hopefully you can find out which app is frying your phone. Good luck.

You say you basically reformatted...would you post what you did exactly? I've got the same issue as the op.

I was having the same problem a few days ago. I wiped all data and did a factory reset. After restoring apps only (not data), my battery is running like a champ again!
Battery was so bad that it was leaking 1%/minute, it seemed like.

Are you guys checking spare parts, which gives you battery usage stats? It's free on the market. Also, do you get poor coverage in that particular area? Constant searching for service def causes battery drain as well.

You guys never mentioned if you did the airplane mode trick and killed the DRM service. Mine drains about that fast if I forget to do those. Even if I do remember to do them, it still drains much faster than it should but at least I can make it through a whole day if I don't play any games.

in the froyo 2.2 betas they have out for the Epic, there's an option to disable data along with airplane mode and shutdown when you long press the power button. You can still get calls and texts when you disable data..
I thought its a neat feature. It should help you if you're running a 2.2 beta rom.

I think the huge drain is linked to the 50% no signal bug. I would always come home from school with a nearly dead phone every day. I began putting it into airplane mode every once in a while to combat the signal bug and now I come home with 70% left.

Same here. I go somewhere on sat mornings where I don't get service (and don't need my phone). If I don't put it in airplane mode, I'll easily lose 30% in that hr and a half.

JI6 update: a *serious* let-down, in my opinion

So, this post is 1/2 "rant" and 1/2 "any ideas", but the JI6 Update has been (in my opinion) a very serious letdown.
First of all, I can't be alone in thinking that the late-September update from Samsung would be a full-blown upgrade to Froyo. Obviously it's not. I guess we'll wait awhile before that's released
Secondly, I'm one of those sorry saps that had the update soft-brick my phone. It took me a few days to get around to the ODIN fix (bumping me back to "stock"), but it was still a royal pain.
Thirdly, I've already seen some issues that I didn't have before. For instance, the phone "froze" on me while sitting at home: no screen response. I had to pull the battery and power up again. Nice!
Finally, the battery life is utterly horrible for me -- and I'm not sure why. Currently at 26% battery life (now 8h 4m since unplugged). 34% of the usage is "display", which has been on for 28m total. 22% is cell standby. 15% is phone idle. 10% is voice calls (2m 10s of that). 8% is the Android System. So on and so forth. Basically, I've *hardly* used my phone today, yet the battery isn't going to last thru to the afternoon. I have 6 active applications, with none of them hitting the CPU at all currently. Best of all? The battery icon looks like I'm about 1/2 full, so evidently Samsung couldn't be bothered to make that icon accurate. I know about the battery icon mods out there (I've used 'em), but I figured Samsung would take care of that.
Sorry for the venting, folks. Is anyone else seeing similar stuff? Any ideas on the lame battery life??
Thanks,
Yip
For me Android 2.1 which samsung released in Galaxy S is exactly like Windows Vista ! No matter how many updates you release for it still will make your phone **** !
The only option is to release a full new OS which is Windows 7 = Froyo !
Better than Windows NT = 1.6
Getting your phone bricked isnt the updates fault, there are hundreds of threads out there and reading just one couldve given you signs of warning.
As for your battery life, I am willing to bet your phone screen is full of widgets. Try limiting those, as well as automated syncing. I get excellent battery life that can EASILY last me the whole day (I actually find myself running avatar/pandora at the end of the night just to drain it so I can recharge the battery).
However, I do agree that the inaccurate battery reading should have been fixed a long time ago (or at least in this update) and that froyo should have been included with the release of this phone.
Your cell standy is too high which means you have things constantly using the cell signal to pull data, thus draining your battery. Right now I'm at 72% with 67% display, 14% voice calls, and 9% cell standby. Been unplugged for 3 and a half hours.
Not great but I'm purposely trying to let it die because I'm reconditioning.

Ha! You may just be right on that. Eclair seems like a fairly lame version of Android, if you ask me. Not horrible, but not great.

"Signs of warning" means nothing, my friend. There are folks who didn't even *root* that got soft-bricked with this update. It was (somehow) poorly handled.
As for your widgets comment, well... you would've lost the bet. I use a single screen, no widgets, no weather stuff, bluetooth off, wifi on (but currently turned off), and nothing extraneous. I run Android about as light & frothy as you can get! I prefer speed over just about everything.
Any other thoughts, though? Perhaps I should re-load Autostarts to see if there's anything strange launching at boot time...

Interesting. Any ideas what would be pinging the cell standby so much? I'm in a high-bandwidth area (full bars), so it's not like the phone is struggling to get signal. I use Gmail and Exchange, but my Exchange sync is set to "hourly", rather than push.
Doesn't seem like I'd need to disable my 3G connectivity. I certainly have never had to before.
You should probably reflash the update. JI6 was great on my phone, no hiccups, no lag, perfect GPS.
Also, you should recalibrate your battery after the update and give it a few days to settle down. I always get horrible battery life after flashing a rom, but after a few cycles I'm back up to 24h+.

Honestly, I wouldn't know unless I knew your full setup. What I will say is that I do have a lot of widgets and apps running that pull from the internet but yet my cell standby isn't as high as yours. I haven't reduced any of my sync intervals either. The 3G radio can really drain battery fast, faster than even the screen so that is a problem.
Also, in JI6, they increased the strength of the radio so it drains even more battery. I am running the JI6 modem however.
You should use something like WatchDog to see what is constantly running and using CPU. That could give you an indicator of problem apps.
Well, I'm disabling some startup items: Visual Voicemail, Telenav, and Daily Briefing -- none of which I use. Maybe that'll help. I don't know...
I was really trying to run "stock" this time around -- not so much fooling and tinkering with things, but it doesn't appear to be paying off for me. Frustrating.

Oh wow, yea definitely you need to disable all of those. That's the first thing I do. I actually uninstall Visual Voicemail, Telenav, Amazon MP3 etc. ALL of those things constantly run for some reason even without you opening them once.
You're not alone. My battery life is terrible as well after the update. I'm losing 4% an hour on standby.
That said, my phone is smooth and working great when I do use it.

Again, if you didn't do so after the update, wipe battery stats and then do a few full drain/charge cycles. My battery life always sucks after flashing a new ROM, but it always goes back to normal given time.

after the update for me, my gps is much better, but i actually have more lag then i had stock before....
so I need to either flash a kernel, lag fix, or a rom with at least one of those.... its kind of frustrating to have lag just from opening or closing a simple app, messages, or call... I honestly cant believe a phone with these hardware specs can have lag just from somthing as simple going into the dialer and exiting out...
Battery life seems to have decreased a little but still getting a good 20+ hours. GPS is a little better with use wireless networks. Lag is an issue now though. Didn't have much before a the update. Hopefully its solved in another update or froyo.

So I applied the update on Tuesday through Mini Kies. First experience with this update, it's been great. My phone seems to faster, really I hardly experience any kind of lag or slowdown (and this is in comparison with my stock vibrant running OCLF). Battery life even seems to be better, but that is probably to do with conditioning. So everything has been good except for the fact that my phone has froze on me TWICE today. I'm thinking it's something to do with the apps though. I was in Layar and it was working for a bit when suddenly, it froze, I didn't have to pull the battery I just held the power button down for a good 5-10 seconds and it restarted. The other time was in a game, which kind of concerns me. I suppose I can reinstall both and see how that goes. I'm thinking it has more to do with the apps possibly being corrupted. The first thing I did was install the 2.2 market on my phone and I ran the update all function on like 15 apps that needed updating. Not a good idea imo, the market went crazy and forced closed a couple of times. I'm not entirely sure what is going but it seems like my phone is only freezing in certain apps. I hope it's not just some random freeze that can happen at anytime, that wouldn't be no good.
You guys complaining about battery life... i would Love to have your times. I got 3 hours and 8 minutes today on a fully charged battery.

3rd day with phone, 2 self resets already

Ok, so what happenned on the 2 instances that this happenned was all of a sudden I lost cellular signal and the phone made a sound and the signal bars switched to a circular sign with the line across it. I put the phone in airplane mode but nothing happenned, within a min phone restarted it self...
The phone is stock. No root or anything like that.
Ps... using the keyboard to type this, and its much easier compard to my old droids kb.

Weird. Haven't experienced that before myself. I have had it lose signal and display the circle with a line through it but it's not very often and only for a second or two.
Just did it again when I went into pandora. I realized its actually not resetting, but the phone freezes up and everything reloads. Including signal and 3G... the screen shutz off and you can't turn it back on until it reloads

I had the same problem on my original Epic. I had three problems in total on that phone.
Samsung's crap coding that caused the phone to not sleep. (fixed after 2nd update)
The phone would randomly restart itself
During calls, the screen would freeze while illuminated. The call wasn't interrupted, but aftwards I had to pull the battery.
In the end I had to exchange the phone for another. Only problem was, the new phone had that couple millimeter gap with the slider. Sprint said it wasn't enough for third exchange though.
Man, this sucks... Just when I put all the apps I wanted on it and got it running the way I want it...
I'm gonna give it 1 more week see what happens, then return perhaps for another epic. I'm pretty sure I'll be sticking to the epic though, i really like the camera capabilities of the phone.
I'm actually going to run 4 tests this week
I'm going to leave the phone untouched from 10:00 to 21:00 and note the percentage in battery with juice defender on/off and also noLED on/off, see what happens... to make it even, i'll just leave the phone in my car, and it won't be used except it's usual email checking/texts/missed calls etc.
my droid unused for that period of time usually was around 80%. it was running a custom rom with 1 ghz kernel as well, so same power requirements i'd say. except epic has a bigger battery.
Battery is pretty bad with the Epic but Im not surprised at all about that. I have about 50% right now with heavy texting, a few phone calls, and listening to music. 8hrs unplugged. I think it would make it to 14-15 hrs easy with heavy use.
Phone calls kill the battery the most I believe.
And I'm using Juice Defender.
Mine was dying with heavy texting, some GPS and browsing within 6-7 hours, no phone calls....
I did a little test today.
When I'm at the police academy my phone is in my car from 1000 to 2100. My rooted 1ghz droid would be at 80% by 2100. it'd get it's regular share of texting/emails and all that I couldn't look at until 2100.
I did the same thing today with the Epic, with juice defender, it was at 79%, so pretty much exactly the same...
tomorrow I'll do the same test with JD off and see if it makes a diff

I have just installed Juice Defender (free version) and using it as installed. I'll see if it helps. I have a question about the status of TRAFFIC, it is listed as "Leave Data/WiFi enabled while >50KB/15s", what does this mean? I can guess that JD will leave the Data connection ON, even if it is scheduled OFF, if the phone is sending/receiving data at a rate greater than 50KB/15s. Is this close?

I am having the same problem with my phone suddenly. If I have multiple apps open, such as radio, browser, and facebook at the same time, it seems to cause it to reset itself. It's not a full hard reset, but more of a soft one, screen goes black and everything starts up as if the phone was just turned on.
Maybe it's time for a replacement?

The only way you could have that on a stock battery is have the phone off and battery pulled out for 34 hours.

keep an eye on your TWS. This has been a huge issue for me, and keeps draining the life out of the battery. Only solution so far seems to be the ariplane mode toggle work around.
I was able to make 30+ hours on a single full charge with dk28.
I still haven't put eb13 through its paces but from what I'm seeing, its great with battery.

if you all want better battery life then disable your data network ...the way to do this is hold down the power button ...just like you are turning your phone off, you will see the data network. hit that button..it will disable your internet constantly running in the back ground and also will disable notifications...you can turn it on at your discression when you want to check your email, internet, or anything pertaining to data network...but trust me this will give you alot more battery life..also you can install setcpu and clock it to run lower when your phone is charging, not in use , or even when you are using your phone...this also helps substantually...good luck guys

Very nice suggestions I'd also like to add that using Wifi will use a LOT less battery then 3G probably 80% of the time. At work I have poor reception so leaving 3G on will kill my battery, however WiFi it's not uncommon I leave work after 10 hours unplugged with only 20-25% of the battery used! Make sure to set the wifi sleep policy to never if you go this route, that way it never goes back to 3G even when sleeping.
Turning data off completely and using the phone only lightly all day at work (a few text messages) (10 hours unplugged) i've left work with 88% percent battery remaining
Battery life has improved greatly. I turn off background data, stop the Omadrmblablabla service, no live backgrounds, but it is full color. With moderate use I can see 10 hours and still have 40% before I go to bed.
My battery life has been greatly increased too. The battery indicator seems much more accurate too. I did the factory reset several times, then wiped and used the samsung installer.

I wish I could be as lucky as you. This is by far my biggest complaint with eb13. I have tried flashing multiple times to no avail. How did you update? odin, samsung exe, update zip, or ota?
I did an odin flash, and my battery is much better as well. On 2.1 stock I would usually get about 16 hrs with my usage. Now, with the same usage on EB13, I can get about 36hrs (charging every other night).
I did the zip update first, and my battery was awful and only lasted for 4 hours. But since the odin flash, everything is great!

TWS = time without signal. Airplane mode resets the radio on the device and somehow fixes it (albeit, temporarily). I read somewhere on here people believe it has something to do with the fact that, for some reason, the phone is looking for a gsm signal as well as cdma, and since this is not a gsm phone, it obviously can't find a gsm signal. The constant searching for gsm is causing a drain on the battery. This happens in areas with full sprint coverage, like my house. For whatever reason re-setting the radio forces it to stay on cdma mode only. I think i read someone saying something along the lines of it being a problem because this is was an update created for devices across the board, ie, for both cdma and gsm handsets. Its just a bug that needs addressed. Some people have it, some don't -- which is even more frustrating!
If you are not experiencing this problem, please tell me what method you used to update. I have only tried Odin (and update zip once), so I will try the samsung exe to see if it does anything.

Post LTE Upgrade Xoom Battery is Horrid. Any fixes?

Got my LTE upgrade done on my Xoom and now the battery is a joke. I went into settings and disabled the LTE connection, so that now 3g is only used. I also turn wifi on when at home. Currently my Xoom is draining 4ish% per hour while in standby. That means this damn thing won't last a day just sitting there, locked, with no screen on. In Honeycomb 3.0 and 3.1 I could get a days of use with 4-5 hours of screen on time and about 22-26 hours of total unplugged time. Now, under 3.2.2 my battery is totally dead after 18 hours of unplugged time with around 1-1.5 hours of screen use. This is virtually unuseable for taking notes in graduate school after work, when being close to an outlet is impossible.
Any ideas as to what's going on? Tried using Watch Dog and System Panel to see if any apps were going nuts with random CPU usage or RAM usage and everything seems to be in-check in terms of system resource usage. Considering I have 4g totally turned off and wifi enabled when I'm in range of wifi (most of the day) I don't have a clue where this power drain is coming from. Any assistance is highly appreciated given how much I rely on my Xoom for day-to-day use. 3.2.2 seems to have killed it for me.
Please help! Will try any suggestions.
Thanks.

Have you tried disabling mobile data entirely? When I'm in wifi, I disable the cellular connection but haven't performed any in-depth trials on battery life.
"Settings" > "Wireless & networks" > "Mobile networks" > deselect "Data enabled"
Its not just you, mine is the same way it sucks big time. There really isn't anything that I've found to fix it.
I loved how I used to be able more than a day out of a charge...
Anybody have any ideas? Maybe undervolt kernel???

I haven't but this isn't feasable. I use mobile internet for everything and even take notes and such on Google docs. Even though I'm near wifi for most of a given day, I shouldn't be bothered by manually turning mobile data on and off just to have power- mobile data should be mostly killed when wifi is active. That's how this Xoom worked before. A tablet without internet is nothing more than a paperweight to me. 2 classmates with LTE upgraded Xooms are having identical problems. No fixes found yet. Any other suggestions? This battery life is really, REALLY bad.
Tried going a factory reset and battery life is the same, horrid short, running nothing but stock apps.
Any other suggestions?

Same problem here, but I have the mobile network completely turned off and it still does this! Even with the switch to CDMA only!
I will keep reading this thread (only read the about half the posts before posting) so hopefully a solution will show up. But you're not alone in the horrible battery life post LTE upgrade!
I've had my Xoom back since last Wed.
No higher battery drain than previously.
I'm on wifi 90% of the time in home and office.
Yesterday I was all over north San Diego county using 4g. Got home with 60% charge which is about the same as for a prior trip with 3g.
Put your xoom back the way it was. The new hardware sucks the battery a little more. Buy a thunderbolt and then say the xoom battery life sucks. Never charged it during the day before the upgrade. Oh well, that's the price if 4g.

Currently my Xoom is draining 4ish% per hour while in standby. That means this damn thing won't last a day just sitting there, locked, with no screen on. In Honeycomb 3.0 and 3.1 I could get a days of use with 4-5 hours of screen on time and about 22-26 hours of total unplugged time. Now, under 3.2.2 my battery is totally dead after 18 hours of unplugged time with around 1-1.5 hours of screen use. This is virtually unuseable for taking notes in graduate school after work, when being close to an outlet is impossible.
Any ideas as to what's going on? Tried using Watch Dog and System Panel to see if any apps were going nuts with random CPU usage or RAM usage and everything seems to be in-check in terms of system resource usage. Considering I have 4g totally turned off and wifi enabled when I'm in range of wifi (most of the day) I don't have a clue where this power drain is coming from. Any assistance is highly appreciated given how much I rely on my Xoom for day-to-day use. 3.2.2 seems to have killed it for me.
Please help! Will try any suggestions.
Thanks.

Download Auto Airplane Mode by DON from the market. It will help BIG TIME!! It does just what the title states, it puts the Xoom into airplane mode automatically as soon as the screen goes off. When you turn the screen back it, the data comes right back in 3 -4 seconds and you're good to go!
Also, you don't have to uncheck any settings or turn 4G off.
Update: Mobile data completely turned off, on wifi only with Xoom sitting about 4 feet from router all morning, so wifi signal was strong. This is the first time I've used the device today. Unplugged at 330am my time, its now 130pm. Device battery is at 60%. 10 hours and 40% of battery gone. That's with mobile data 100% disabled, wifi only- can't even get the Xoom to standby for a full day now. At this current drain rate, it would go from 100% to 0% in one day with no mobile data usage, no screen on time and no usage other than syncing Gmail every 2 hours.
Brother who commented above: Thunderbolt will standby for a full day with no screen on time on wifi only and it has under 1/3 the Xooms battery capacity. I should know- my wife has one and it now outlasts my Xoom. That should not be the case.
From my understanding the Xoom has two 3225ish batteries set up in a sequence. My battery life actually seems to be about half of what it was before. Is it possible that one of the two was disconnected during the LTE radio installation and not properly reconnected? Wasn't sure of the details of how the batteries were set up, but if the Xoom could function with the second battery not working, seems like that would precisely half battery life. Anyone familiar with exactly what had to be done internally to upgrade the radio? Looking at the ifixit teardown of the Xoom, the batteries cover the whole backside- looks impossible to do any internal work on this thing without removing them. Any thoughts?
Cheers,

Same here. Can't get a full day out of it. Hope a fix will be comming up.
Thunderbolt got the he-man battery and modded my otter box to fit. The xoom battery has entered the battery hog realm after the lte radio. As far as I can tell the radio is cdma/lte together. And it uses power even if wifi is on and data off. It's what I would call big brother watcher. Even if your not connected the radio is txing and rxing something. You know it's lojacked!

Interestingly enough, removing the LTE SIM card and using wifi only made no improvement to battery life. I'm assuming the new radio is running at 100% all the time without throttling down, even if absolutely no connection exists or there is a string of faulty battery reinstalls in which only one battery is providing power. That might explain why some people seem to have greater battery issues than others.

im glad im not the only one with this problem! its pathetic! im taking my charging cable from my dock with me to work so ill have at least some battery life when i take the train home in the evenings
i to am glad that I'm not alone with this either. I use to charge mine every 4 days with no wifi on and almost no use. Now I get about a day with no use. I mainly use it for web searching and dungeon defenders when I'm home. Horrid battery life for doing nothing. Luckly I mainly only use it at home and am almost always on the dock I got from motor from the upgrade. I use about 4% an hour also with nothing on. Mine is completely stock with no root.
Yahoo mine is stock with absolutely no root or other mods. I guess they knew about the pissy battery life and that's why they gave a free dock. Lol. Still trying to find exactly what's killing the battery. LTE does drain a lot of juice but as I've stated before my wife has a Thunderbolt and per mW of battery power, the thunderbolt is more efficient and that's not saying much. It can standby for over a day with no use fine and it has roughly a little less than 1/3 the Xoom battery capacity. Something isn't right. Its not supposed to be this bad. Anyone filed a complaint/tech request with moto/Verizon? I think its something that we should all do and report what they say here. I have a feeling more and more people are gonna have this issue if they do the upgrade. Maybe if enough of us make some noise, something will be done.

Maybe it's not the radio.
3.2.2 may have some kind of interaction with something you guys were running that's causing wake locks to get stuck
Did you look at Settings:About Tablet: Battery Use ?
(tap on the histogram at the top for another, see if the time spent awake is solid or different from screen on)
I tested this on mine, with the mobile data disabled and lost about 1% battery every hour, this is on par with the performance I had pre-upgrade.
Rooted, stock kernel
I realize it does not help you but you might look somewhere other than the wireless radio for the problem. I unplugged my upgraded Xoom yesterday morning around 8:30 AM. It is now 8:20 AM and my battery is at 66%. I was on 4G for about 2-3 hours yesterday, the rest of the time on wifi. I check and respond to my mail on the Xoom so it saw some use yesterday, though not as much as I normally do.

R800x 2.3.3. battery life absolutely deathly

Okay so I posted here a week or so ago about how my Xperia Play was epicly failing....it was force closing everything and dying in just hours.
So I factory reset and used Titanium to restore all of my apps and stuff...and so far the crawling speed/force closing has for the most part abated (opening up texts and contacts still sometimes takes forever or force closes)
but the battery issue remains. My battery is absolute garbage at the moment. It drains by 10 percent per half hour if being used or even more!! And it gets hot constantly, and obviously at that time it really sheds the power and dies quickly.
If I'm CHARGING the phone WHILE using it heavily, it WON'T power ABOVE the % it started at!! It stays constant or goes down!!
I'm not sure what to do. Should I let the phone die, keep it off, and charge it while off till its 100%?
Or maybe my phone is approaching the situation it was a week ago...I constantly check the running apps and its the usual suspects, nothing crazy. I had to delete official facebook app because it almost ALWAYS lagged and oftentimes force closed.
It says cell standby is using 40%, wi-fi using about 22%, voice calls 17%, phone idle 15%, and dialer 14%
What happened to my phone? Why is it such a clusterf*ck lately? Any ideas/advice?
Are you leaving wifi on because that will really suck the battery down? Also do you live in an area with bad signal? Put it in airplane mode and see if the battery still discharges as fast.

My r800x dies in 6 hours whether it's on airplane mode or not. I've re calibrated the battery like 5 times so far, and it just won't get better. I'm regretting moving to verizon to this. I should just get a sim card and go back to my HTC Inspire. I can leave the r800x in idle with the screen off, while in airplane mode and it will still die in 6 hours. It doesn't even last a whole day of work. Mine's also rooted. I need some serious help with this phone.
Turn off wifi.
If you have it on it will search for wifi networks all of the time (unless you're home and connected to your own wifi) and it will suck your battery dry.
I don't even use wifi. I don't have access to the router at home, and my data is turned off when I'm not using it.
Perhaps you have a bad battery? Maybe replacing that will solve the issue.
It could be. Every time I try to check my battery's health, no matter what app I use, or even if I do it from the service menu it reads at "unknown". One app says that my phone doesn't even have a battery stat service, or something along those lines. I was considering just buying one of those mugen batteries for my phone, considering that I brought the issue to verizon's attention, and they told me they were gonna send me a replacement battery, but I never got it. This was all about 2 months ago though.
wow, sounds bad. mine will last all day, its an r800x on 2.3.3 as well but i can use it like normal, play about a hour of games on it, talk on it a lot, use wifi and 3g and do some average surfing and it will last at least 24-30 hours...
i'm thinking it must be a bad battery as well
Im running 2.3.3 verizon from the FTF and my r800x would last almost 3days, and thats with texting/talking/surfing using 3g and playing a shyt load of sonic . I would replace the battery with a genuine Sony replacement, dont ever buy a ebay knock off ! Furthermore, I don't believe apps that check your battery health are accurate at all, so dont waste your time.
Best way to check (imo) - Before you charge it up, let it go to 0% and die. Boot recovery and wipe the battery stats, turn the phone on and charge to full. After its fully charged, let it sit 10-15 mins on charge. Then pull of the charge and use normally, if it still dies fast, replace the battery.
If this idea was already posted sorry for double post
How do I go into recovery? My boot loader is still locked. As much as I want to unlock it to put abc xperia play rom on, I don't want to pay 25 bucks.

You cannot boot into recovery without an unlocked bootloader

I swapped mine out for similar issues. The replacement doesn't have the same issues yet but I haven't put a single app on it. I can't say that adding apps caused it before because I remember it similarly not getting anywhere when charging while using. I also experienced it dropping while charging but it turned out to be a that the MTP device wasn't starting on the PC so it showed as plugged in and charging even though it wasn't (check the Device Manager). My Alienware M11x actually supports charging devices off that particular USB port when it is turned off so it was a bit hard to figure out when it seemed to charge some times and not others.
So I got a new battery. Battery life oz still terrible, phone still can't detect battery health.
Not sure why, but my battery voltages are higher than 3.6 :/

Hate to tell you but it sounds like your Play is defective.
The only way it would always get hot like that is if it was always running, that would be mainly driven by being in a REALLY bad service area that its always searching. I have a boatload of games etc on mine and my battery life varies from 2 days to 3/4 of a day depending where I am. Heck my battery life varies as to whether I leave my phone on my desk at work or on the shelf above me (lasts longer on the shelf).
But the fact you said that even in airplane mode it eats the battery, and a new battery didn't do the trick. I would say you got a bad one. Still under warranty I hope?
i'm not entirely sure. I got mine through verizon in august or september of this year. Not sure if Verizon would handle replacing it, since I didn't buy their extended warranty. I read somewhere that SE themselves can handle it since it's not a year old yet, but my phone is kinda required for work.
