Hello.
I'm using nexus 7 2013 lte for a couple of weeks and i experience some troubles that quite bother me. Device is running android 4.4.2 installed OTA.
First of all, battery drain in sleep mode is kind of unpredictable. At night (8-9 hours to be exact) device can consume 3%, 5%, 15 or even 20. My first thought was to check installed third-party apps which could cause it. But i didn't manage to find the reason of the problem, the statistics of battery looks OK, tablet can work fine for a couple of days, and then same thing occurs. I found no dependance to 3g and wifi on/off: there can be 3% for night when device is just left with wireless connections, and there can be 10-15% with airplane mode on and precursory reboot. Battery drain happens only in sleep mode, and battery times are absolutely normal on heavy tasks (10 hours of 720p video, 3:45 of gaming). The other device I use works just fine with same apps installed, same settings and cellular carrier: consumption on idle is low and constant.
Some weird jumps in battery level also can be noticed: from current level to 100% and back on: example 1
example 2
No chargers or usb were connected, temperature around was constant. Can't find any reasonable explanation to these jumps.
So should I suspect that my item has any hardware faults of battery, or there can be some software issues?
And another minor question: how good should be wifi reception on nexus? The "other device" I mentioned above (which is galaxy note 2) has solid, good level and speed of connection, while nexus seems quite worse on this subject. For example, in the room where I am at the moment, note has 3/4 bars in wifi symbol and fine, constant speed, and nexus has 1 or 2 bars of 4, and connection looks pretty laggy.
Thanks in advance for any response.
Try factory resetting and testing sleep mode battery consumption again without installing/touching anything. If its a hardware problem, it will happen again. Wifi reception should be the same or better then note normally, but as i said, factory reset and try, if the problem(s) persist, its a hardware problem.
Those battery graph peaks were still present last night.
I've just performed factory reset, will see if it changes behavior of my device.
Thanks!
So, after factory reset on pure system without any non-stock apps I got these results:
Battery consumption on idle was usually between 1 and 1.5% per hour. There was a little of instability (marked red on the screenshot), but just a little. Nothing like sudden 15% per hour that used to happen before. Is 1.5% good enough for sleep mode on stock firmware with 3g(not lte, 3g) and wifi turned on?
No jumps to 100% were noticed during these 24 hours, but they didn't happen every day. They worried me most, so I'll continue to check if they occur again. Hope they disappeared after factory reset.
As for the next step, I gonna install my usual apps and see if it affects battery perfomance.
By the way, about wifi reception: it still had 1-2 bars where galaxy note has 3-4. But then I ran some speedtests, and connection speed on nexus was usually significantly faster then note's. So wifi works just fine, it is just a matter of wifi icon calibration.
For a bit my batt life was suffering. I found it worked to turn it off, charge it fully, and then turn it on again. I actually wanted to know if there r any good task killers for it?

This started on suiller's ROM guide, but I feel it's really OT so I should take it outside.
I've had battery issue ever since I got the Diamond. With moderate use (maybe ~15-20min of call per day, email check every 30 min, moderate web browsing) the battery level can drop by ~ 15-20% per hour on average. This means the battery would only last 5-6 hours without charging, which is not good enough to last through a day.
I first looked at whether the phone has any serious battery drain application, and it doesn't. With BatteryStatus I see the battery drain is ~ 100-150mA with GSM on, BT on. When I'm downloading email, or browsing the web, it does go up to 200 ~ 300mA briefly, but that is only when it's transmitting / receiving data. In standby mode with screen off it drains less than 50mA. These numbers seem pretty typical from my experience.
And here's the weird thing - on a typical day, when I wake up, and take the phone off the charger, it can drop from 100% to 93% within 30 min. On the way to work, when I would browse the web lightly, it can easily drop from 93% to 80-85% within an hour. That's pretty bad battery life.
Yet there are instances when I've been browsing the web, or playing MP3, or using YouTube for a good 10-15 min, but the battery level would not drop.
I figure maybe the battery needs to be re-calibrated, so I decided to discharge the battery and recharge it. I know this doesn't help improve the battery life of LiIon batteries, but I was trying to recalibrate it.
What happened, when I was discharging the battery, was I found the battery drop was very quick from 100% down to ~ 50%. From that point on, the battery drop is much slower.
And from 50% to 25% the battery seems to last forever. The most interesting thing is with the battery down to 15%, I did a lot of 3G web browsing, listening to MP3's, turn wifi on, and that 15% of battery lasted a good 3.5 hrs with heavy use until it's so low the phone stopped working.
The whole discharging process ended up taking 10 hours, and that's with HEAVY use for the last 3-4 hours too. That's actually acceptable for battery life (not great, but at least it'll last me through a day outside with moderate use) and obviously doesn't jive with the 15-20% drop per hour when I'm operating in the 50-100% full range.
When I'm charging the battery, I also noticed the level went up from 0% to 70% very quickly ... pretty much over 40 min. BatteryStatus shows it's being charged at +600-700mA.
As the battery gets full, the charging is much slower ... BatteryStatus shows it is charging by ~ 100-200mA only.
With the battery level up to 99%, it took almost forever to finally get up to 100%. I think it took at least 20 min.
So after a full discharge - recharge, I used my phone as normal this morning to see if it's been calibrated, but nope. It still drops from 100 to 93% within minutes of doing virtually nothing, and easily drop to 80% after an hour ride to work.
Does your battery perform the same way? Should I replace my battery? Or is there a way to properly calibrate the battery?
btw location and reception has nothing to do with it. I have good to excellent reception throughout this test.
I'm having the same problem but not with every rom (don't know wich ones, tested almost every rom hero) So is this a piece of software wich shows the live that doesn't work ?? or is it the battery ? As i can see it it's depending on rom thus it's not hardware
But hey I'm n00b
i've noticed that a soft reset or power up will use 3-7% of battery depending on the weather (what else could it be )
don't have the ability to discharge but i agree that in many cases the battery usage drops drastically & there is no reasonable cause
hope someone can figure this out!

1. discharge the battery completely (by playing video, audio, etc.)
2. Remove the battery and wait about 1min then place it back (do not power on the phone)
3. Full Charge the phone, wait when LEDs stop blinking (do not power on the phone)
4. When fully charged - remove the battery (do not power on the phone)
5. Wait about 1min then place the battery to the phone and now you can power it on.
If battery is more or less OK it will re-calibrate.
I hope it will help!

Thanks. I tried those steps yesterday and my phone is pretty much behaving the exact same way after the battery cycle.
After all the steps, the battery shows it's 100%. I unplug it, and it drops to 97% within MINUTES literally. Now I plug it back in, and it takes forever to get from 97% back to 100% (> 1hour)
I think it may be a battery problem and not a calibration problem. The drain averages ~ 120-150mA when phone on, screen on, no data, and below 100mA with phone on in standby mode. That seems pretty typical? I'd think the battery should last longer than 8 hours (till it completely dies) in that case.
Where do you guys suggest I buy a new battery for the Diamond (other than HTC directly)? I bought one from DealExtreme but the battery runs ~ 10C hotter than normal all the times ... I don't think I want that as my primary battery.
If you get through a full day with moderate-heavy use on your battery, I say that is normal and good battery life on a Diamond. So, why bother that the percentage is not proportional? I would not get a new battery for this since the problem is only in the reported percentage, not the battery life itself.
I've had plenty of cars that went from full to half tank on the meter significantly faster than from half to almost empty. You know about it and adapt to it, simply.
Hello !
I'm understand you, i have a ELF (Touch P3450), and a Diamond, the same problem appear for the two phones!
Every Morning, when i disconnect from charge my diamond, my level battery go to 93% in 10mns without reasons (One sms, no 3G, no Wifi etc).
My battery go down to 50~70% around 14H (2H pm), and stays at this level for many hours (4-5hours ~), i think it's not a problem with our battery, but a dysfunction of the sensor battery, which shows wrong data =/
By the way, that problem doesn't appear every day, for example, today my battery has that level : 83% (15h43), so today it has a good level.
Since i have flash that ROM : http://forum.xda-developers.com/showthread.php?t=521941, with radio 1.13.25.24, i have less less issues with my battery, it's more stable!
That's all, hope that helps you.
Ok guys, I've made a few discoveries that I figure I could share with everybody. Maybe you'll find it useful.
Last week I went on a trip and turned off the data connection while I was out of the country. Instead of letting the roaming charges kill me, I was relying on wifi to check emails and browse the web.
I ended up checking emails just as often, because where I worked had wifi AP.
Now, I could usually get 8, maybe 9 hrs out of my battery with moderate use before it's completely empty previously. So I was very surprised to find that with a similar usage pattern, but using wifi instead of EDGE/GPRS I still had 30-50% battery left at the end of 8-9 hours day everyday during the trip. I know data uses a lot of battery, but I always thought wifi drains even more, so that's quite a stunning discovery.
Now, I don't think it was due to wifi draining less than GPRS/EDGE (can't be true), so it must be something else. In trying to figure out what made the difference, I did a bunch of tests after the trip, and this is what I find-
1. Data channel dis-connection / re-connection is BAD
I used to always set my phone to auto-disconnect data channel (EDGE/GPRS) after 5 min of inactivity, in an attempt to save battery. What I found, was keeping the data channel open does NOT actually drain more battery than leaving it off at all. Transmitting data drains battery, but not leaving the channel open. However, disconnecting it, and re-connecting it all the times actually drains quite a bit of battery. I set my phone to check email every 30 minutes, and then there's also the odd weather forecast that needs data channel. In a 9 hrs day, that means channel disconnection + reconnection of about 40 times.
The last couple days I have left my data connection ON all the times, and I actually get more hours out of my battery. My battery used to drop ~ 10-15% per hour with moderate use. By keeping the channel on all the times it's been kept to under 10% per hour!!! I've only tested it for a couple days. I'll report more on it once I get to test it for longer, but the idea that 'keeping data connection off when you're not using it to save battery" seems to be a complete myth. The opposite actually saves battery!!!! And as a bonus, I don't even have to wait for the data channel to connect when I need it!!
2. Recycling the radio is VERY BAD
Everybody knows 3G is a real battery killer. However, similar to EDGE/GPRS, keeping the 3G channel open does NOT drain any more battery than turning it off, or turning on EDGE/GPRS channel. When the data channel is idling, it doesn't matter whether it's on EDGE, GPRS, 3G, or even completely turned off, the battery drain is close to zero in all cases.
Now, you do see a 1.5 - 2 times battery drain with 3G compared to EDGE/GPRS, so I've always turned 3G on only for web browsing or watching YouTube, and use GPRS / EDGE for regular emails update. The thing is though, if you're not transmitting much data (which you won't for regular email update), the difference in battery drain is minimal. SWITCHING between 2G and 3G though, requires a radio power cycle (turn off then back on to switch frequency) and THAT drains a lot of battery!!!
So if you're often switching between 3G and 2G, and you only transmit little data in 2G mode, you might actually be better off keeping it in 3G all the times instead of forcing the radio to power-cycle all the times.
I've tried keeping it in 3G all day long and I noticed minimal increase in battery drain. However, there might be another reason you want to consider - RADIATION. 3G not only drains more battery than 2G, it also transmits at a stronger power than 2G and as a result create more radiation. For that reason, I'm still keeping my phone to 2G for email updates and what not, and switch to 3G only for web browsing. For radiation you may try this thread if you want to read more about it.
3. VGA screen is a REAL battery killer
I do quite a bit of reading on my phone (ebook, on-line magazines etc) and reading ebook was never a battery concern in my days with the Touch (QVGA screen).
That's why I was quite surprised on the Diamond, reading the ebook for 1 hour, with EVERYTHING else turned off (GSM, EDGE, GPRS, 3G, BT, wifi), my battery level went down by 12% in ~1 hour.
The VGA screen drains a lot more battery than the QVGA screen. Now, if you need to use the phone you need to use the screen, there isn't much of a choice. It does make sense, however, that if you're using the screen for a while (like reading ebook) switching from a high brightness level to a lower brightness level.
Oh, and the auto-adjust brightness thing? That doesn't help you save battery at all. This is because it polls the light sensor every 2 sec (default value, but you can change it) and adjust screen brightness accordingly. This mechanism drains battery in itself, and in most cases end up using more battery than keeping the brightness constant at a low to medium level.
The auto-adjust thing is cool, and in theory it sounds like it can save you battery, but unless you constantly set the brightness to max even when you're in a dark environment, disable the auto-adjust and just set it to a constant 50-60% instead.
These are the few things I've noticed and I'm still trying things out, but over the last 2 days I've seen a significant drop in battery drain. I would be lucky to go through a 8-9 hrs day with moderate to heavy use before, the first 2 days I tried this I still had 60% battery left after 5 hrs of moderate use. The Diamond is very weak on battery life so every bit helps! I hope these tips are useful to you!
Thanks for your share

It's exactly what the charging process is supposed to do.
Read more here:
The charge time of most chargers is about 3 hours...
Increasing the charge current does not shorten the charge time by much. Although the voltage peak is reached quicker with higher charge current, the topping charge will take longer.
Some chargers claim to fast-charge a lithium-ion battery in one hour or less. Such a charger eliminates stage 2 and goes directly to 'ready' once the voltage threshold is reached at the end of stage 1. The charge level at this point is about 70%. The topping charge typically takes twice as long as the initial charge.

hello guys,
i flashed the radio to 12.62.60.27p_26.13.04.19_M after which i flashed update-LC-ICS-1.0.beta4-DesireHD-signed.zip by wiping completely. During standby, the drain was very less (about 1 mA , occasionally reaching 5 mA.) After 24 hours, the drain increased beyond 10 mA, sometimes even reaching 40mA or more in standby mode. It was only after i rebooted the device, the drain is somewhat acceptable now.
Is this normal or something is wrong? what could be the reason?
in the above cases, the phone was in standby mode, no calls, no data, only 2G. the only difference in the second case was additional applications like facebook, etc but no data, no sync.
btw, i just rebooted my phone and lost battery level from 3.735 to 3.691 , drop of 14% as shown in current widget.
any suggestions ?
I'm running cm7 and for me that's quite normal.
The drain per 5 minutes is between 1mA and 10mA while in 2G standby, screen off, data off.
The drain of course jumps up to 40mA to 200mA if the screen is on and i'm using the phone (wifi on, using google reader etc)
Getting 1mA per 5 minutes all the time sounds a bit unrealistic to me. Maybe in airplane mode and no screen on time.
I guess your problem could be the additional apps. Maybe an app is running wild?
And might i ask what you mean by "battery level"? Are you talking about the mV?
First of all, make sure you're are really wiping everything. Just to be sure, you may follow this steps:
http://forum.xda-developers.com/showthread.php?t=1226016
You can also take a look in your battery stats, the battery usage of mediaserver. In come ICS based ROMs, it drained battery a lot.
I tested LCs 1.0.v4 and also got poor battery performance, may be inherent to this ROM.

hi, standby => night time when no screen is on...
it was about 1 mA most of the times and occasionally reaching 5mA

hi, yes, i have been following the link for wiping since the time i sarted flashing ROMS..
but what you are saying could be right.. the ROM itself could have battery issues...
I'm running LC ICS v1.2. I haven't seen any significant battery drain though I'm using an Inspire 4G. There's also an undervolting app on the second post in his thread. Undervolting has improved the battery performance slightly as well for me...
I'm running CM10 10.0 Stable and the latest Lightening ZAP Kernel.
I've always had problems with battery life that are somewhat random. Sometimes my phone will last over 24 hours with the same usage as when my phone decides to die in 8 hours. This is very concerning because I know a phone should not be this random with the same apps and usage charge after charge.
I've relentlessly searched for the wakelocks that keep this crazy phone awake using BetterBatteryStats, CPU Spy, Battery Monitor Widget and GSam Battery Monitor. My average charge time on a rooted stock 4.0.4 was about 20 hours. My average time on CM10 stable is 8 hours. I now carry around an external USB battery all the time because of this with a wall charger and multiple micro USB cables in my arsenal.
Now I'm playing with undervolting but I know that's not getting to the source.
My phone does seem to go into deep sleep when unplugged but only 50% of the time. I've read that VBUS_PRESENT is when charging with a non friendly charger. Well I've been using a stock Samsung charger that came with my phone and it still shows up. WLAN_RX_WAKE I'm totally not sure of...it uses a huge amount of time keeping the phone awake why?? I'm not sure. It didn't used to do this and I leave WiFi, Data, and Syncing on. I have the same outcome whether Google Now is on or off as well.
Any help would be really really appreciated. I think I have battled battery run time since I started using Android. I wish it wasn't like that because I love the openness of the operating system compared to iOS which I have used in the original iPhone and every generation up to the iPhone 4. If you guys require screenshots I'd be more than happy to give them. There are so many smart minds here that know far more than me and I know it!!
I'm having the same issue running Gangnam Style CM10 on my Evo 3D. I'm seeing huge wlan_rx_wake wakelock that I haven't seen on any other ROM (same networks).
Apparently, it's multicast network traffic that the phone should ignore, but instead wakes up and replies.
Sucks.
Hmmm strange. I reformatted my phone and wiped everything clean...and reinstalled CM10 stable with the newest lighting zap kernel. But now the phone app is taking a massive amount of power from wakelocks and CPU. My phone is left with a higher than average CPU idle running at 1566MHz for 40% of the time before my battery dies at 10%/hour. Something is really up and I can't figure it out. I know that when my phone was operating at 4+ hours per charge the temp would be under 30C. Now running at idle it's 33C. I normally never feel the back of the phone heat up near the camera LED but now it sometimes feels warm or hot when it's deciding to try to deplete power within a few hours. This is a strange thing....I don't hear of people with CM10 having this problem...or does everyone think having an 8-10 hour burn time is normal?
Just switched to Slim Bean ROM (JB) and still have wlan_rx_wake jamming me up on wifi networks.
u guys need to change the settings under the advanced menu to tell your phone when to enable/disable WiFi sleeping, the delay amount, that's what the wlan_RX wakelock is
as the op stated,vbus is indeed when using a charger other than the stock Samsung one that came with your phone
What should the delay amount be? I used to have it set to 5 minutes under "only when plugged in". I use my OEM Samsung charger and nothing else but I still get vbus.
I just did a test and turned all data and wifi off. Battery drain has been completely normal at less than 1%/hour. This is great so now I need to find my internet culprit. I get the same type of nasty battery drain with Wifi on, Data on, Wifi & Data on.

I'd rather have the wifi never sleep. Why use a low speed, higher power radio (3g) when you have access to a wifi network.
Wlan_rx_wake never kept the phone awake on gingerbread ROMs.
I updated my Samsung Galaxy S3 (Sprint) from Android 4.1.2 to 4.3 the other day via USB cable and Samsung's KIES software, and it first everything seemed fine. The phone seemed to respond faster and so I was happy with the update. However, in the past 24 hours or so, I've noticed some major battery / charging issues.
First, last night, I charged the phone up fully while watching TV around 8ish, and by 10 or 11 it was almost dead again (and I hadn't really been doing anything on it during that timeframe). Then, overnight, I had it plugged in to charge, and when I woke this morning it was EXTREMELY hot (the battery I assume) and had a message stating "Charging paused - battery temperature too high" although it seemed to be almost fully charged. I turned it on to airplane mode, left it unplugged, and went back to sleep for a little while longer, and when I woke again it was much cooler and the battery had hardly drained. Now, I just turned it off airplane mode and it's getting slightly hot (although nothing near how hot it was earlier) and the battery seems to be dropping at a much more rapid rate - from 93% to 90% in the past few minutes.
Anyone have any ideas?? Do I maybe need a new battery? Just an FYI - I'm not using the USB charger that came with the phone - I've been using others - could that make a difference?
Any help is greatly appreciated! Thanks!
I expect that it's probably the same problem that I described in my topic. In short, if you disable wifi location reporting you should experience much better battery life, but if you want to use location reporting you'll have to wait for a fix.
So, one setting that I've changed that has helped has been: Settings -> Connections tab -> Wi-Fi -> Advanced -> Keep Wi-Fi on during sleep -> Always
Now, when I'm at home (or elsewhere that I have a constant, good wi-fi connection), my battery actually lasts most of the day. However, I still notice that when I'm out and about, the battery drains extremely quickly. It seems (although I'm not 100% on this), that it drains faster when connected to 3G than when connected to a 4G network. Still, I never had this issue when I was running Android 4.1.2, so I'm wondering if anyone has any other optimization or configuration change tips that might help me get my battery life under control?? Thanks!!
Install Cyanogenmod and fix the battery problem
I cannot post the youtube video. Here is the link youtube.com/watch?v=MOql56YgEDU
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.
