Battery life? Is it really that bad?

Gizmodo and MobileCrunch have pretty much bashed the battery life to make it sound like if its not on the charger, it will die in a matter of an hour or three. For the people who got one from the I/O or other means. What do you get from the phone during a normal days usage? If its that bad, have you guys use SetCPU/Locale/App Killers etc? Thanks.

With light to moderate use, it lasts through the day. A bit worse than Nexus One in that respect, but not too bad.

Agree with sergey.povzner.
Android central had a great review on this. I have heard a mixed bag of battery life. Some sounded very good some didn't. But it's the most power smartphone out there so additional drain is expected.

It not as good as my n1 but its close. It gets a lot better with custom roms without sense.

Uptime 10:08:35
Awake time 1:46
I had it plugged into computer for about 25 mins to transfer a movie.
I have 80% battery left.
No bluetooth, no GPS, no WIFI.

I don't have anything extra except gmail and another account frequently syncing. I get 4-5 hours of browsing and email with 4g on or off, wifi off, gps off. Standby time doesn't seem to have significant effect though I'm sure it would be measurable if you left it in standby for a day. Adequate to get me though a day, but I hardly use voice.

What if you are watching full length movie on HTC Evo, how long will the battery last (especially if I put it on airplane mode)?
I am planning to switch from from Xperia X10i to HTC Evo. My x10 has the usual battery drain problem but I have controlled it with task killer. However, I am yet to run a full movie on it. If x10's battery life has more survival time (with task killer on it of course) then HTC Evo then I might think twice.
Also can the 'task killer' improve HTC Evo's battery life?

Does anyone know if the Evo uses the HTC Touch Pro size battery like the Hero?
If so then I've already got an external charger and three extra batteries!

Honestly if anyone is that worried about battery life get another battery as a backup. Its been said many times on these forums that a HTC Touch Pro 2 and also a HTC Hero all use the same batteries as the EVO. (Confirmed). You can pick them up on ebay for around 7 or 8$. Which is pretty cheap! Nothing better than having an extra juice pack laying around waiting to be used! Hope this helps somewhat

LOL we posted at the same time, thanks for answering my question! I'll keep a backup in my glove box and one in my back pocket. This method worked great with my Hero.

i'm so excited, wish I had an extra battery though, it'd be nice
8hrs 15min till i get mine!

Gotta say this thing blows my old Moment's battery out of the water... 4.5 hours hard and heavy use... 60% left - no 4G coverage area (but it was left on by accident - ooops) and no video watching, but heavy text, email, and facebook/twitter activity.

I ordered the extended slim battery from seidio.com. 1750 vs 1500. Should give a bit more in the long run.
Its been decent for me though. Just dont jack up your brightness, keep it on auto.

Wifi kills my battery. The signal never settles even though the coverage should be good all over my house.

You want to go into advanced wifi settings and change WiFi sleep policy to never otherwise your phone will shut off WiFi after 15 mins of screen being off and you'll be using 3g which will use a lot more battery.

Mybattery was pretty terrible. Lose 10% per 40 minutes on standby mode alone. After messing around with it for a while I discovered the culprit was the location services. I turned them off and now I lose about 2% per hour on standby.

I'm curious, how exactly do you go about turning off the location services? Unless it's included with the GPS tab of the settings, I haven't been able to find such an option on my brother's Hero.

It's under settings , location and then location setting. This does not disable the 911 location which is good.

Losing battery at about 8-10% every hour on idle

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?
Sent from Epic 4G

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.
sent from my RAZR

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.

Improved battery performance by turning off data roaming ?

Hi all,
Now I've not tried this myself however a friend of mine who recently got a DHD said he was lucky if the battery lasted a day on a full charge however by turning "Data roaming" off (even though he is not roaming) he is now getting anything between 2-3 days on one charge

Data roaming was turned off by default on mine and still the battery drained pretty quick.
Using data of any kind will affect the battery badly. Notes Traveler on my device is the cause of it needing charging every day.
Same as any phone, the more you disable the longer the battery will last.

If everything was implemented correctly by HTC, turning off Roaming should have no impact on battery life at all (provided you don't use Roaming).
I believe that your friend experienced the typical warm-up phase. For some (a lot?) people the battery life is terrible when they first use the DHD, but it gradually gets better.
Your friend probably attributes the increase of battery life to the disabled Roaming, while it is just a "natural" process.

I'm roaming all the time, and my battery is actually pretty good. If i don't use it much it can easily survive two days. My record is three days with light usage. (That was with the stock 1.72 ROM)

What is data roaming anyway???
Sent from my Desire HD using XDA App

Data roaming is set off by default. And data roaming controls data transfer when you are not on your home operator/network, i.e when traveling.

are your friend meant data connection?

He probably means "3G" off? I've had mine since the end of October and got into the habit of charging the phone every night. But then wondered about the effects of turning off wifi and 3G as, currently, I'm at home most of the time and have a PC with 24" screen to play with. Anyhow, with 3G and wifi turned off most of the time I get 3 days or so from a charge. I haven't investigated turning just one or the other off as life's too short ....

PS: and someone will say, well what's the point of a smart phone if you're just using it like a dumb phone? Well, the "smart" bit here in this case is me ....

Yeah, 3G uses a bit, so the first thing i did was to disable it. No point for me using it actually, since it's WiFi all over the place here i live. If i need it, i'll simply enough just toggle it on.

And btw 3g doesn't actuality use much more power when compared to wifi, if you always use it somewhere where the signal is always poor then it's another thing.

If I meant 3G then that's what I would of said. So just to be clear, there is an option "Data Roaming" that when turned on will enable a data connection when you are in another country. My friend claims that while on his home network he has turned this option off and he has seen a big improvement on battery performance. If this is true or not I'm not sure, I just simply thought I would share his thoughts with everyone else.

I did this, once i remembered where it was and I got my old battery life back. So thats a bonus, not having to take my charger to work!

Using System Panel graphs to monitor battery drain I'd concluded that 3G drains battery at about twice the rate compared to wifi.

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.

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.

Tab S5e horrible standby battery drain

Last week I have purchased a brand new S5e, and overall I am pretty happy with it, outside of one big problem: the damned thing loses like 30-40% of full battery charge per day while sitting in my desk drawer, doing absolutely nothing. This is, frankly, unacceptable. My two-year old Galaxy Tab A loses 2% per day when idle, so I would kinda expect similar idle drain from the new device as well, given they have similar-sized battery (7040 mAh in S5e vs 7300 in Tab A).
I have tried:
Uninstalling unused bloatware via ADB pm uninstall
Turning off data and wifi
Turning location off
Restarting the thing
"Sleeping" of all the apps via Samsung's battery save features
Factory resetting the tablet and repeating the above with no extra apps installed
Tried the "Extreme battery saving" feature, but frankly, that leaves the tablet in absolutely unusable state because it limits you to like 5 built-in apps and portrait mode. Who the f uses their 10" tablet in portrait mode?!
Currently trying Airplane mode, will see how that goes, but I'm not keeping my hopes up at this point. -- Update: Airplane mode seems to have satiated its hunger for battery, but that's not really an option to keep on at all times. Any other ideas?
I'm frankly running out of options here. I bought this for xmas and it's, tbh, unusable in this state. It does have the latest software update from Samsung (October 1st, 2019).
I've tried running BBS to shed more light on what's going on, and while it's showing the device is spending nearly 50% of the idle time in "Awake (screen off)" state (compared to 2-4% on my tablet and phone), but neither Kernel nor Partial wakelocks show anything egregious. And normal battery stats are about as useless as you'd expect, too.
Currently considering taking it back and asking for a return or RMA, but figured I'd ask here first, maybe one of y'all has encountered the issue and by chance knows what's the problem and how to fix it.

You need to take an idle log with BBS and post in the BBS thread asking for some analysis.

Remind me, how do I do that?

Naptime by Francisco Franco will turn off Wifi / Data / GPS when the screen is off, and turn it back on when the screen is turn back on. Works best on Rooted devices though.
I'm using Lineage 16 on my Tab S5e, I generally get somewhere between 7-8 hours of SOT, and go 5-7 days between charges. I use Naptime on all my tablets have for a long time. Found it doesn't work as well on cell phones. I haven't paid attention to what my idle drain is, but overall my battery performance has been excellent with Lineage.

I have figured it out.
Turns out, the tablet has some issues with the provider's sim card and plan. I got internet-only plan and it does not allow for neither outgoing nor incoming phone calls. And my other tablet has a normal calls+data plan. When I swapped cards between the two tablets the drain issues also swapped! Except the older one wasn't draining nearly as fast, but still noticeably enough. While new one only lost 1% overnight.
So looks like I will be staying with my old plan, maybe upgrade it a bit. Oh well, no big loss, but mystery solved.
