Anandtech preview, troubling battery life tests

Check it out. Doesn't seem to bode well for motorola's baseband. Hopefully they're quick to toss out a new radio. Cell standby has easily been my largest drain in the past few days.

Those two take up my top as well. Thats my point, simply idling eats up the battery worse than even on my thunderbolt.

How much will a new update to the radio do for the Bionic? Didn't the TB initially have terrible battery life because of its original radio software? Can someone clear this up for me? Thanks.

I have over 28 hrs on my bionic currently and still going. I'm at 30% as of right now. Phone has been off the charger since 0630 yesterday am. It is now 1422 on the 13th.

The thunderbolt has been through a ton of (leaked) radios. I think the consensus was that the OTA radio was a big help.

Also in the boat with standby and idle as the top battery consumers reaching 40%+ of the battery life depleters.

My Bionic goes for almost 24 hours between charges. So i don't care how much cell standby time it uses. it is getting DOUBLE what my thunderbolt does under the same usage.

idk
The battery life on my new bionic got better when/after.
I conditioned the battery! enormous difference from first couple charges.
Realized that, once again my phone cannot replace my TV, Laptop, blender and wasnt going to help my kids behave better. It is my phone.
I installed juice defender! Huge difference. really like the app
Like a watched pot never boiling. If you stop watching the battery meter go down it actually DOES stop going down. Amazing.

My battery life is mixed 3g/4g.

droid 3 poor battery life, vs droid 2 global

This is just a rant.
I have droid 3 for about 2 weeks. I notice that D3 life is far worse than D2G. For the same usage pattern of me, I usually got about 4 days out of D2G. But for my D3, I always get less than 2 days of usage.
The culprit seems to be "cell standby" (there was another thread on this). My D2G always got about 5% on "cell standby" however, my D3 always got over 35% of power usage on "Cell Standby".
End of rant.

Sounds to me like someone needs to switch Carrier Mode from "Global" to "CDMA".
Unless you severely hack your phone or travel outside of the US, you won't need Global mode.
This prevents the GSM radio from switching on.
Also, Cell Standby will be used frequently when you're in a weak signal area. The best solution to that is to switch cdma mode to "Home Only" and use Wifi if you're using data apps. Strong Wifi uses less battery than weak CDMA.

Actually two days of usage without a charge is pretty good. That's about what I get with my extended battery and fairly lite usage. A couple of possibilities: 1) you now have a dual core cpu which is much faster than your D2G but probably draws more power. 2) You may be using your phone a lot more. I know when I switched my wife from her Droid 1 to her new Droid 3, at first she was complaining of poor battery life. Trying to trace that down I looked at her data usage for the first month she had it and it had more than doubled from about 500 MB on the last month with the Droid 1 to over 1 GB the first month with the droid 3. See, it was her new toy so she was playing with it a lot more than usual - particularly since the phone is faster which allows her to do more with it. We are in the second month now and data usage seems to be getting back to a more normal level.
The point being that when its new, the tendency is to use it a lot - even if its just getting it all set up the way you want.

Battery drained in 5hrs.???

Hey guys Thanks for stopping by, I've seen many posts like this which I really didn't want to post but I ran out of options... Im. Currently running on gingervolt 1.3/ blitzkrieg+ 2.6.35.7, I hope you guys have all the info you need. I leave it running over night and when I leave for work in the morning at noon its already powered off because no more battery... Please let me know if there's something I can do to make it last longer... I'm not the type of person that uses the phone all day.. Thank you

Should be in General not Development, And why don't you just shut the phone off until you go to work?

You can try: Setting the CPU lower with an apk like CPU master, CPU set, ROM toolbox, ect.... Turn down the brightness of your screen. .. Uninstall some of the apk that are always running in the background... Turn off LED message alert. Stop using apks like advanced task killer (unless you custom set it up to not kill system vital apk.) Turn off 4g unless in an area that has strong 4g sig. Recalibrate your battery after a full charge. Install GingerVolt 2.0. Buy extended battery (still $25 @ vzw website)
There are many different things you can do to get more battery life out of your phone... Look in the GingerVolt forum and check out where others have done. But get a custom to bringing your charger everywhere you go.

Not just turn off 4G but turn off data and wifi. These 2 radios are constantly working. The more time with them off the longer the battery will last.

My own experience and take is that daily battery life depends on good cell signal. I live at the fringe between three cell sites. My signal is typically two bars or less. At work I have a similar situation, but shielded by building opposite the cell side.
I always stay plugged in because my battery is always being used otherwise. My guess is that people who report much greater battery life are lucky enough to be in areas with good signal strength.
As an example, this morning I got up 1.5 hours ago, took the phone off the wall charger, rebooted it and used it a bit during my morning prep. I left home an hour ago with the phone plugged in to the car charger for 20 minutes (which charges at the lower USB rate). I have been at work for 40 minutes off charger since and now have 90% left on my EXTENDED battery.
At home reception is 3G most of the time. Work 4G.

yeah I agree, turning off 4G is not an acceptable solution....
GV2.0 unmodified with a cpu tool worked fine for me but I have gotten accustomed to having chargers with me wherever I go (home, office, car)
We are hearing battery life is much improved on ZV8, so maybe that will help too with the next GV release....

V8 battery life for me is now crap. I have gone from about 3% per hour usage to 7 to 10% usage and that is with almost no usage of the phone. This is sucking. I am about to roll back to v7 if this does not improve.

Not sure how your phone is different. Maybe you need a new battery or possibly a new phone. Forgot my phone at home during work today. I'm at 86% after 9.5 hours.

I've got the same problem he has except it got worse after I went to Gingervolt 2.0. From what I've read on here it seems that not wiping date may have something to do with that so once he gets the new update incorporated into Gingervolt I'll be doing a complete wipe and trying from there.

Killing a battery by keeping it topped off or cycling it. Which is the greater evil? This type of battery has a number of discharge life cycles. So, stressing by keeping the voltage at max or consume those life cycles? I don't know, but I certainly want to have it most available, and keeping it charged works for me. Some people don't let their fuel tanks go less than 1/2.
In the end, I have way more battery, extended and spares, to care if keeping it charged up is hurting the battery because I only have it until the next upgrade in a year.
Ideally, I would prefer to change the charge scheme so it wouldn't run the charge voltage so high maybe to 95%, to protect the battery further. But, in my time frame, doesn't matter.

I run JuiceDefender Ultimate and it helps quite a bit. I'm using it in aggressive mode on Gingervolt 1.3 ROM, and ran it with stock before that.

I personally don't think hes killed the battery.
I have two because they gave me a special on docking station that came with an extra battery when I bought the phone. Anyway I sleep during the day because I work night shift. If my battery is almost dead I pop a new one in before bed otherwise its at about 97 percent after I got home from work. When I wake up 5-8 hours later I've lost almost 50 percent. Sometimes more from either battery.
I check the batter usage stats and Android System is up at about %97 percent...
I have all notifications turned off except Gmail and theres no WiFi or anything.

Google Tech Support says Patch for Battery Drain Coming Soon

I decided to call Google Tech support for the answer to ask whether the ear piece buzzing is causing battery drain. That's my only concern. I don't care if there's a buzz (the iPhone 4S had it, as did the GN, as do a few other phones).
And the fella I spoke with says the earpiece buzzing is not the father of your baby (/Maury mode) -- I mean, not causing battery drain.
He said it's a manufacturing defect and they'd be happy to send a replacement unit (I said, sure) but he assures that they've looked into it and it's not causing battery drain.
He went on to say Google is planning to send out an update very soon to patch a few bugs, including battery drain issue.
The gentleman sounded legit, but who knows. I hope it is true.
I urge y'all to call Google Tech Support and ask the same. Let's see if there's any consensus.

Pretty certain he's correct,
Hasn't every nexus phone received a fast point release update that fixes a ton of things, improves performance and battery?
Doubt they would change that with the Nexus 4.
It would have been 4.2.1 but due to the December bug, it will have to be something else (4.2.2 probably lol)

wtf is this "battery drain issue?"
For as long as smartphones have existed, people think there are:
- Battery drain issues
- Wifi issues
- Freezing issues
Most of the time the first is caused by a rogue app or bad reception or a combination of both. The second is usually a router issue, and the third is usually a combination of apps interacting or a cell phone that has too much crap installed that just needs a clean wipe.

+1 on the "bad reception" part. I just got a signal booster from T-Mobile for my house (I work from home). Before installing it, my battery was generally around 10% by bedtime. The last two days it's been 40% and 50%. It's a very noticeable difference.

I'd love to get one of those but I don't want to shell out several hundred dollars.

Yeah. Android phones perform notoriously badly with low signal. I lost 30% at work in 1 hour because it kept trying to sync. Compare that with usually going home with 40% left.
Anyway I'm not saying battery can't be improved on this phone. But there really isn't a drain issue present.

Then how would you explain that most nexus 4 drain over 2-5% per hour while idling around doing nothing?
And how about you fix, for example, the msm_hsic_host wakelock that's active up to 50% of the standby time? Come on, I'm sure you can do it with killing background apps!

Yes, custom ROMs are already addressing certain issues. the battery drain and other stuff are definitely present in the stock firmware.

Guys, there are a lot of battery issues threads & guides & faqs and whatever on XDA. Look, for example, for one in my signature. Though it's for my previous device, most of things are still relevant.

There certainly is an issue which I've been suffering. Note in my case there is nothing recorded in the usual battery usage statistics to pin point any problem.
I found overnight and excessive daytime power drain in my case is because the CPU isn't entering deep sleep (using CPU Spy). Typically deep sleep should be in the 90 plus percentage range of all states. In my case it was spending 90% or more in the 384MHz state, so it was never really sleeping, and hadn't entered deep sleep at all, it was an unused state! This causes two problems, one, even though the CPU power drain is small, it adds up over the course of a night or day and eats power, and two, it also means the OS is up and running, so all applications are alive and any app that wants to ping home, download some ads or sync is free to do so which means the cell connection is constantly being kept active trickling packets of data back and forth, causing even more power drain.
Yes an application that has permission to stop the phone from sleeping is often the cause, in my case however battery stats showed no application keeping the phone awake, so I was baffled.
After a lot of troubleshooting I think it might be an issue with applications writing to the emulated SD card, perhaps keeping a file handle open, and this stops the phone entering deep-sleep at a low level in the kernel. As it is happening deeper down outside of Android it doesn't need an application with a keep awake permission to keep the phone awake, and also evades androids battery stats.
In my case I was running Bootlog Uptime, a small app with no permission to keep the phone awake but it does have permission to modify the contents on the SD card and I assume updating a log file on the SD card during the period the phone is awake, probably in order to detect a crash. As soon as this was uninstalled, even without restarting, my phone started deep sleeping.
Now overnight in flight mode it started out with 82% battery, and 9 hours later still had 82% battery! Now out of flight mode, it's been on for a few hours and has just dropped down to 81%.
Note that his application is running happily on a Nexus 7 and HTC One X without causing any issues, hence I think there is some driver in the kernel for the Nexus 4 that is incorrectly refusing to allow the CPU to deep sleep if it sees some activity in the flash memory.
Regards
Phil

I simply can not get good battery life with this phone!

I've been a 32GB unlocked HTC One owner since day one. Battery life for me has been very mediocre, barely enough to make it through a work day with light to moderate usage. For some reason this phone drains so much on standby it's ridiculous. Last week I finally gave in and decided to root. I've found that standby still sucks but the screen uses less power so I can get more screen on time on average. I'm running InsertCoin with ElementalX kernel and for every hour of standby I lose ~3+ percent of battery! I'm not even using the phone! I have EVERY APP on my phone Greenified, Google Search, Gmail, and Play Music uninstalled, I have the phone undervolted and monitor everything with Wakelock Detector and GSAM. Nothing looks weird to me but for some reason my standby still sucks. I've literally crippled my phone and have all location services turned off and I still can't get good standby time. My iPhone 5 could last forever on standby, literally 3-5 hours without losing a single percent. I've been using Android for years and the only phone that got GOOD battery life was the Note 2. At this point I'm considering going back to it because I'm sick of micromanaging my phone and still not getting good results.
Is anyone else having similar issues? There are some people here getting 6+ hours on screen time with ridiculous numbers like 38 hours without a charge. I can't get anywhere near that even with the screen on the dimmest settings. I don't understand how there's so much variation in battery life. I don't play any games or watch movies on the phone, just simple social networking and music for 30 minutes a day.

The HTC one isn't the best phone when it comes to standby time but still,I find battery life to be pretty good, super easy to get through a work day. Maybe you have an app that is running in the background and draining your battery. Install betterbatterystats and try monitoring your apps. That's all I can think of. Also take a look at the battery stats thread and see if folks can help you there.

As you are well aware, there can be a myriad of causes. I just want to recount one example where I made a settings adjustment which cut my battery life by over half. I doubt very much this is the reason for your poor battery life but perhaps others may benefit.
About a month ago I purchased a brand new router. Being a tinkerer, I was fiddling with this and that on the router trying to optimize everything. I also played with the phone and amongst various settings I decided to turn on "best wifi performance". The One has the warning about "may consume more power", but I did not think much about it as I knew I had very good battery life and believed that a bit more power would probably not change matters that much.
Later on in the evening I saw that my battery life was horrendous and I started scratching my head as to why it had gone to hell in a hand basket. Finally, I recalled that I had adjusted "best wifi performance" and did a search on this and found a thread on another forum.
I turned it off, recharged my phone and followed battery life keenly. 24 hours later, I could see that my battery life had returned to normal (normal being between 4-6 hours of screen on time over the duration of a full charge).
Interested if the mods will lock this thread in that they may feel that this should fall under the battery stats thread.

Later on in the evening I saw that my battery life was horrendous and I started scratching my head as to why it had gone to hell in a hand basket. Finally, I recalled that I had adjusted "best wifi performance" and did a search on this and found a thread on another forum.
I turned it off, recharged my phone and followed battery life keenly. 24 hours later, I could see that my battery life had returned to normal (normal being between 4-6 hours of screen on time over the duration of a full charge).
Interested if the mods will lock this thread in that they may feel that this should fall under the battery stats thread.

Wow thanks. I was starting to wonder what crazy app I downloaded. Forgot I was messing with settings. Lo and behold that option was checked. I didn't have it checked when ibfirst got this phone and had awesome batt life.

Battery life of the One is pretty good for most people but there are some issues for some of us and lately some apps have updated and introduced even more bugs causing drain, I'll list some of the causes I found:
-msm_hsic_host wakelock bug on kernels pre- android 4.2.2
-location bug in google play store 4.1.6, fixed in 4.1.10
-whatsapp post juli 1st update (and the one before)
-htc usage reporting (on by default on s-off devices)
-reporting location setting on (in maps)
-some sim cards might not work to well which cause more frequents wake up (eg. in the netherlands vodafone sim cards with a serial number starting with 7 )
to properly debug you need wakelock detector and better battery stats (free here for xda users, search for it)
Edit:Just got an update for Whatsapp (and Facebook and Skype all at once), let's hope it fixes the battery drain.....

Maybe undervolted too much.

Where's the source of S-OFF activating this HTC usage reporting and how could I confirm this? I've seen a few users reporting this but where is the evidence? Would any battery apps pick this up?
EDIT: I think I just found it:

I only undervolted by 50mV in Aroma. Maybe I should set it back at standard?

I bought a packet inspector and found it causes a lot of wake ups, like every minute or so....

I've been a 32GB unlocked HTC One owner since day one. Battery life for me has been very mediocre, barely enough to make it through a work day with light to moderate usage. For some reason this phone drains so much on standby it's ridiculous. Last week I finally gave in and decided to root. I've found that standby still sucks but the screen uses less power so I can get more screen on time on average. I'm running InsertCoin with ElementalX kernel and for every hour of standby I lose ~3+ percent of battery! I'm not even using the phone! I have EVERY APP on my phone Greenified, Google Search, Gmail, and Play Music uninstalled, I have the phone undervolted and monitor everything with Wakelock Detector and GSAM. Nothing looks weird to me but for some reason my standby still sucks. I've literally crippled my phone and have all location services turned off and I still can't get good standby time. My iPhone 5 could last forever on standby, literally 3-5 hours without losing a single percent. I've been using Android for years and the only phone that got GOOD battery life was the Note 2. At this point I'm considering going back to it because I'm sick of micromanaging my phone and still not getting good results.
Is anyone else having similar issues? There are some people here getting 6+ hours on screen time with ridiculous numbers like 38 hours without a charge. I can't get anywhere near that even with the screen on the dimmest settings. I don't understand how there's so much variation in battery life. I don't play any games or watch movies on the phone, just simple social networking and music for 30 minutes a day.

Although I have pretty good battery life when screen on (~5-6 hours), I have noticed the same drain as you when phone is in standby. The only huge wakelock that I have found is called 10113, AudioOut_4 or system*wakelock* mediaserver. I know that this process is for audio output but its draining like 20% of my battery when standby I was wondering if you have noticed this same wakelock on your phone?

I whatsapp and check Twitter news apps sometime a game.
And i can do easy 12 hours max 17 with this usage .

I was just thinking of the good battery performance I've been getting from the handset so far funnily enough.
I think it's been very good after only a couple of days with it.
Been using it moderately to heavy and it's held up pretty well. Over 13 hours now. Maybe it's certain apps u are using that's giving u problems with high drainage.

What are your sync values set at for all your accounts...anything constantly updating will drain battery quickly

25% battery used for 1hr screen on time and 11hrs of standby

I got mine FIXED !
I was having similiar problem with my HTC One tends to overheat a lot resulting in poor battery life. I tried every known tricks to get better battery life still no hope. Went to HTC Care in my area and told about the issue they immediately took it for repair (the phone was only one week old). After like waiting three days I got my phone and back there was a paper which describes about the repair Its said in the problem description "Display Abnormally and Battery Calibration issue" I dont know what they meant with display abnormally they really got fixed my battery life. Before I used to get 6 to 7 hours of battery life now I m averaging a day or two with moderate to light use. I m satisfied ! :good:

I think you misunderstand what overheat means. The HTC One does NOT overheat. You feel the heat more cos of it's metal body, which is releasing the heat through the metal surface. It's directing heat AWAY from the internals, unlike the S4 which uses the same chip and keeps all the heat inside cos plastic is a terrible heat transfer medium.

I know that but mine was like 48 C at the peak when its hot which is very uncomfortable to hold that's why I said overheat. Anyway now its fixed and I don't have any complaints.

Also be sure to not use screen lock sounds or input sounds... the lock sound is the worst. I think it causes a wakelock bug that has been on Android since 4.0
