Battery Drain Problem - Solved??

There has been a lot of posts here about battery drain with varying theories about why many people experience this.
My Dopod D810's battery usually lasts me a day before it finally complains and shuts down around 11:00pm.
During this time I had been using Exchange activesync to push email to my device. However we do have a Blackberry enterprise server at work so I decided to remove exchange and install Blackberry in order to see what differences there were.
Imagine my surprise when I found with Blackberry rather than Exchange that my battery is still at 70% when it normally would have been switching off. It has been like this now for over a week. My usage has been normal during that time and there have been no other changes made,
Has anyone else experienced this? I would be interested to hear from anyone who has. Perhaps this is an explanation?
Cheers

"Imagine my surprise when I found with Blackberry rather than Exchange that my battery is still at 70% when it normally would have been switching off."
That's probably 'cos of how MS's Push Mail works, although it only transfers data when really needed, it also pings the server at an interval( default each 8 mins ) just to check if the connection is still alive( if not it'll re-establish it ).
BB doesn't need to( but it does need to be supported by the carrier ).
At least that's what I read.

just a quick post to say that I think the battery drain - for me - is worse when I changed ROM, I use push email for my old ROM and the drain was normally 3 days now with this ROM I find I charge every day. I am doing nothing different from the previous ROM

I have tried several WM6 ROMs by now, and all seem to have the same problem: I get a MASSIVE battery drain, when I use ActiveSync Pushmail over UMTS connection. Also the device and battery gets warm, if not to say HOT.
I tried already different Radio ROMs 1.4x and 1.50.08, still the same.
I would lose about 20% capacity per hour.
However, if I configure the phone to use only GSM bands, there is almost no battery drain.
Any ideas on this? I use UMTS quite a lot for browsing/email and would need pushmail as well.

Same issue here.
I live in the USA and last month I went to Spain and there I was using Movistar as my cell provider with a Movistar simcard everything was working great (UMTS,Activesync Pushmail,videocall etc...) but man like you said,once the phone was switching from GSM to 3G the device starts craving battery like you wouldn´t believe plus the temperature of the battery was kind of outrageous.
So I switched to GSM and everything back to normal in Spain and in the USA,I don´t know what to say other than 3G and Pushmail drain a lot.
I have noticed this with every rom.
Bye

Same story here. I live in the Netherlands with the Orange version of this phone and no matter which rom I use, it always drains rapidly when i used a 3g connection. So after I browsed with a 3g connection I switch back to GSM for push mail etc and to stop the draining.

Battery Life

Hey guys.
I've been wondering.
Lately im using my TP2 (unbranded) quite a lot and my battery dies out fast. Everyone is saying that if your battery life sucks you should try to switch radioflashes.
What is your general battery life, what rom do you use, what radio do you use and how much do you use your phone?
Im using the GTX themed EnergyRom LEO 23-build (apr-8)
Radio: 4.49.25.17
I use it quite a lot and if im lucky i squeeze 2 days out of a full charge.
Keep up the good work guys!

2 days is good battery life

Is it really that bad ?XD

2 days is amazing. With my screen off most of the day I can get 36-48 hours. If i'm on my phone all day and the screen is on I'll get around 24 hours.
And what are you talking about? Most phones I see are lucky if they get to the second day on a full charge.

Yes, actually anything over a full day's use is generally "above average" for this phone.
The best ways you can make sure you get the most out of your battery is to switch off 3G/bluetooth/wifi at any time that you're not using them, and to not leave the screen on any more than necessary (unless it's connected and charging). When I keep those things turned off most of the time, I can easily get up to 2 days (or very close to it) out of the battery...but as soon as I start using any of those more than lightly, a full day of battery is all I count on.
If you do have to use any of those regularly, then flashing a different radio might help...sometimes you'll get more efficient use of the 3G/bluetooth/wifi with a different radio, but trial and experimentation is the only way to know if another one is better for you or not.

Yes, any type of data connection uses up battery much faster, due to the fact it has to broadcast data over the air.
Unless you've specifically turned off 3G permanently, mail, weather and twitter will all switch the 3g connection back on for what they need, and will leave it on (draining your battery) until you manually switch it off again...

"Cell standby" suddenly draining the battery

I only noticed this problem after using BeastMOD for a couple weeks. One day, my battery was almost dead by the time I left work in the evening, and this is not normal at all. I noticed that in the battery history, Cell standby was the main culprit, taking up around 30-40%. I have never seen Cell standby taking up so much power until now.
After having some issue with BeastMOD, I installed Juggernaut about a week ago. It was fine at first, but now I'm seeing the same problem with Juggs too! Does anyone know why this suddenly starts happening, and if there is a permanent solution?
I tried to take a screenshot with Juggs, but something isn't working. Time without a signal is 0%, but this reading often doesn't even show up.

This can occur if you are in a place of low signal coverage for a while. The lower the signal quality, the harder the radios try to maintain a signal.

It could be because of the applications running in the background that takes up the battery while the phone is idle.

Correct. Specially if your radio is constantly switching from WCDMA to GSM due to poor reception. Generally if you're on GSM and you don't have great signal then you wont see a dramatic effect on the battery but its the complete opposite when on WCDMA.

Yeah, that's how I understand it. What doesn't make sense is that this would happen suddenly, and then not let up. The phone would be running fine for a week or two, then suddenly the cell standby shoots up. I'm not visiting new areas that I don't normally go to. This is only at home and at work - two places I spend the most time at. And both of these areas have good coverage from T-mobile.
When it shows it, Cell standby will show 0% for "time without a signal".
I disabled Juice Defender, and I'll see if that makes a difference in the next couple days. So far, it doesn't look like it. Cell standby is at 29% right now - much higher than normal.

Do you use your phone at all during work and home? I leave my phone on standby in school and it is normal for me because I do nothing else at school with my phone. When I get home and start using my phone, Cell Standby disappears. And the percentage next to the process is the percentage of how much of the battery lost it is responsible for. If your battery is at 80%, and Cell Standby says 40%, it is responsible for 40% of the 20% drop in battery, though I'm sure you know that already. I have never seen a case like yours, though. From what I can figure from the screenie, Cell Standby is a huge problem because it is at 10% battery from 100% in 10 hours and 39 minutes and that is really short for standby only. The apps that I see that take up battery are the same system apps on my phone when on standby. Try replacing your battery, and if the problem consists, then I suggest you UNROOT it and exchange it. If they charge you, argue because after all, it isn't your fault. Your drainage is extreme though, because at 10 hours on standby, my phone would have at least 60% battery left.

I use the phone at work, though typically pretty lightly. I don't see how this could be a problem with the battery. The battery isn't telling the phone to do anything, just supplying it with juice. It's very inconsistent, though now I've experienced the problem with two different ROMs.
I've plenty of references to the flight mode "trick", where you turn on flight mode for a few minutes, then turn it back off. I don't know what this is supposed to do to the system. I had tried this before with no luck, so this morning I put the phone in flight mode for half an hour. Currently cell standby is only at 12-13%... we'll see if the problem comes back.
I bought the phone from wirefly, and it was back in October. I don't know if I can exchange it anymore... RMA with Samsung, maybe...

Yeah. Samsung is your best bet since you didn't buy it directly from TMO. I also had the same problem except that the culprit was IMS Service. I uninstalled that, but I'm not sure about your case. IMS wasn't essential. Cell Standby is and I don't think you can even uninstall it.

Are you on an actual ICS ROM? That might be the problem, since we don't have our own KERNEL for it. Try flashing Bombaridier if you are on ICS. GB might fix the problem. Or flash EasyDoesIt which is also an ICS ROM, though I haven't let the battery settle for a couple of days. For the most part, it was normal for me.

I know this is a pain-in-the-ass suggestion, but you might want to try reflash back to stock 2.3.5, do the OTA upgrade to 2.3.6 (which should reflash your modem), and then see if the problem persists. This would completely rule out any kind of software/firmware issue.
I still think it's likely a signal quality issue, though. Not all signals are equal. Just because your phone a strong signal doesn't necessarily mean it has a strong 3G/4G signal. The signal icon can be very misleading and will often display the "4G" signal even when it really is only connected to 3G bands. The radios will constantly try to "step" up to the next band by testing the signal. This process consumes excess battery power. Have you tried setting your phone into 2G only mode and determining whether the problem still occurs? I'd also go ahead and turn off Bluetooth, WiFi, and GPS radios while you are at it.

I just might have to try going back to 2.3.5. I did flash the 2.3.6 stock ROM and was using that for a long time before trying out Beast and Juggernaut, though. Does that not flash the modem?
The reason why I flashed 2.3.6 instead of doing the OTA update was that after I un-rooted and went back to stock 2.3.5, I didn't get the OTA update message and Kies wouldn't update me either.
How do I selectively turn off 3/4G? I only see the "Use packet data" option.

As I understand it, flashing a 2.3.6 ROM does not update the modem. It's the same reason a nandroid backup won't backup/restore your modem. You should be able to find out pretty quick by going to Settings > About > Baseband version. It should be T989UVKL1 for the stock 2.3.6 Hercules modem.

My baseband version is T989UVKL1, so apparently I'm using the 2.3.6 modem.
The problem isn't happening today. Cell standby is at 10% at the moment. I turned off packet data this morning for a few hours, and turned it back on around noon. If the issue comes up again I'll try switching to GSM only and see if that does anything.

The problem came back a couple days ago while I was at work. Around noon, I noticed that Cell standby was taking up over 30% of my battery life, and the battery was draining much faster than normal. I turned off Wifi and left it like that for the rest of the day. I checked the battery usage periodically, and the Cell standby percentage steadily dropped till it was in the low 20's. That was a couple days ago, and I've left Wifi off since then.
Today, Cell standby is at 11% and the battery usage seems relatively normal. I'm at 63% after almost 6 hours.
This makes very little sense to me, but I'm putting it out there anyway. I know there's a problem with one of the wireless routers at work when PCs connect to it, so maybe my phone is having issues with it too. Still, though, I don't know why that would affect the cell radio. There are several different wireless access points at my work, so I'll try those out too.

Do you have wifi calling enabled? If your wireless router has signal problems, this could cause the same effect as cellular signal problems... it could be constantly switching from wireless calling to network calling and never letting the cellular radios enter their sleep states.

Let's not spread false info, our device is not 4G at all. LTE is 4G period.
To the |OP|, 1st off get rid of that juice defender crap. I have ran both ROMS you have named in an area that gets horrible service coverage. I have no problems with cell stand by even with wifi, GPS, data, & sync enabled. I was still pulling about 23-24 hours with moderate use. Enable wifi calling to curb the modem changes when you are in wifi range. Wipe cache, davlik and battery stats. If that persists try the new blaze radio in the dev section. I wouldn't recommend going to stock and OTA to anything. All the stock roms have a bunch of bloat that eat battery and data. Report back your findings and we will see how to help you further if this doesn't fix the issue.

I don't have wifi calling enabled. I tried it a few times when I first upgraded to 2.3.6, but it didn't work very well for me. The sound was scratchy and noisy, so I disabled it and never looked back.
For the last couple days I shut off wifi completely, both at home and at work, and this has improved the battery life. Yesterday, after about 14 hours, I was still around 40-something % (I wanted to take a screenshot, but screenshots aren't working with Juggernaut on my phone). I have been using the phone pretty lightly the past couple days. Cell standby was in the low 20% range.
I will try another wifi hotspot at work to see if that helps. Just curious, what do you have your Wi-Fi sleep policy set to?
Edit: I have had Juice Defender disabled for a while now. It didn't seem to be the source of the problem.

Who has problems with the battery since nougat, too?

Since I have updated on nougat, my battery quickly goes empty.
I reach a maximum of 2 hours SOT.
According to "BetterBatteryStats", the operating system consumes the most energy.
No matter whether Stock Rom or currently with "PureNexus" and ElementalX Kernel with GhostPepper profile, the battery is still very fast empty.
I also wonder what the Wakelock *job delay* and *job deadline* mean.
Now is the question, do you have the problems since nougat, too.
And is the problem the operating system or rather the battery, what do you have for experiences?
With marshmallow I had up to 5 hours SOT, therefore I will downgrade.
Whether it will be better, I will report.

im finding that when my WLAN is off then my drain is negligible. Whilst with it on i see a steady drain overnight.
That might be how i have my phone setup, but not sure.
I now have tasker setup to disable wifi, location, data and swap to 2g at night (i have terrible 3g/4g reception in my bedroom). it seems to help for overnight drain but not daily usage.

I have never had good battery life with this phone, by the end of the day it is usually almost dead with only about 1.5 hours of actual use.

I have the same feeling.
If you confirm that downgrading solve the problem, I will try the same.
Thanks!

Battery has been fine for me. Your phone is never idling properly from the looks of it, despite not being show an awake. Not sure what that means though.
Is there some issue with your WiFi or data signal? I've not seen the WiFi X myself.

I have not changed my settings so far, only slight improvements, which I have since I own the smartphone.
Mobile Data always to max 3g (have no LTE contract), GPS always on (only device), Wifi also always on and could reach thereby also up to 5 hours SOT.
Then I moved from the Google Stock Rom to PureNexus hoping it would help, well, wrongly thought.
And I have always done a clean installation. :silly:
I've been back for a day now on the last Marshmallow Rom (MTC20K) and I do not want to be too rash, but it seems to improve. :laugh:
I will continue to observe and report.

Normal overnight battery drain

Hi guys, I'm coming from a S7 which lost 1-2% during an 7-8 hour sleep, with everything off, now with a brand new S9+ I'm losing more than 5% during the night. I know this isn't excessive but I don't find it normal either when my other phone lost less than half of that. During the first days I used the S9+ without the SIM card and overnight drain was perfect, 2% every 10 hours, but once I inserted the SIM I started seeing a drop of 5 or 6% every night. Once again, I undrestand it's not terrible, but my other phone lost max 2% in the same situation.
So for what I've noticed, it's the SIM card radio signal the major drain, in GSAM it appears as 87% of the overnight drain. Removing the SIM makes it lose 2% overnight, that would be perfect but I can't enable Flight Mode everynight for I need to receive calls in case of an emergency.
Any suggestions?

Have you tried just disabling data? That would stop MMS texts but you'd still receive calls.

Sorry I didn't specify, when I said everything off it was including mobile data. Everything is disabled, only drain seems to come from the phone signal. I always have 2 or 3 bars so the signal is not terribly bad.

Ahh, ok. If there is nothing running in the background and the only thing is the Sim card, then I don't see much hope for an easy fix. Of course, there is the old factory reset that Samsung would suggest but that may be a big PITA for nothing.

Ignore it, you're worrying over 3% battery drain?
Charge the phone for 2 minutes in the morning to gain your 3% back... :silly:

I think it is fine, Your installed app might have increase from the day you purchased your S9 so might might be increasing apps might be reason behind it? but over all why are your worrying about 3 to 5% as long as s9 is running android to your are going to have some percent drop overnight, I think you shouldn't worry about it

Yes, I know it's not a lot, but why my 2 years old S7 drained 1 or 2% overnight and my brand new S9 drains 6% or more? Some mornings I have woken up at 93% having unplugged it at 100%, and it went down to 92% after 20 seconds of use. Can different phones have a different drain because of the modem/phone signal?

I factory reseted it a couple of times and still got a 6% drain in 7 hours, not 3 to 5%. My main concern is that I inserted the SIM in my old S7 for the night and got 2% drain, and next night tried my new S9 and got 7%. That's what I don¡t understand. The drain in the S9 is the same with everything factory set and with my S7 setup transferred. S9 drains 5 or 6% and S7 drains 2% maximum.

The drain in the S9 is the same with everything factory set and with my S7 setup transferred. S9 drains 5 or 6% and S7 drains 2% maximum.

You're comparing apples and oranges. The S9 has a lot more under the hood and that's probably contributing to the extra usage. I think you may be chasing a ghost.

Thanks for all the replies.
I see, so even though the phone is asleep and with everything off/disabled, the faster processor might consume more battery? I understand your point, yet I only see the drain when the SIM card is in the phone, when I take it out the drain is equal to my S7, 2% in 8hs max, that's what I find strange.

If this is just 'because you are interested in what's causing the extra drain', and not because it's actually bothering you, then by all means try to narrow it down, but S7 vs S9 = completely different phones separated by 2 years, new tech, you can't expect them to perform identically, including power consumption
That said, my S9 probably drains about 2% a night, but I've used a package disabler to kill a load of useless system apps, possible one of them is causing the drain
AOD will drain too
You up to date with firmware?
Tried flashing a different CSC region stock ROM? Possible the modem (CP) is causing the drain if it only happens with the SIM inserted (I'm running O2U)

News, I have reseted to factory settings but didn't connect to wifi so the phone doesn´t download any carrier bloatware or update/install other apps. Drain from 8PM to 7AM was 2%. I will try tonight again without modifying anything except for what the phone installs automatically. If the drain appears again I will start disabling bloatware until I find the culprit.
Thanks a lot for the help. It doesn't bother me a lot, but a drain of 6 or even 7% sometimes during the night is a bit annoying. That's half an hour SOT I lose.

Surely you're back in the house before your phone reaches 7% though? Would be a very rare occasion when that last few % actually made the difference between having power or not
But like I said before, you don't get up and leave the house in 30 seconds, plug it in while you get ready if you really need that extra 30 mins
But yea, carrier bloatware could easily be the culprit, hence the package disabler pro (no root needed)
Or flash an unbranded stock firmware (BTU and XEU are carrier bloat free in the UK)

Why should the region of the firmware influence the drain? All firmwares should be the same. In theory.

Certain CSCs enable certain features, VoLTE / WiFi calling, call recording, etc etc, and for example if BTU and XEU which are both UK unbranded were identical, they would surely get the same OTA at the same time, but they don't, and carriers add their own bloat if you have a CSC that is carrier branded
Also changing CSCs often requires Odin's repartition option to be enabled as the firmware requires different partition size vs the original CSC that was on the device when bought
Different modems I would imagine for different regions too, if the drain is coming from a SIM related issue, the modem part of the firmware would be a suspect

I read that there are issues with the modems on the S9 some time ago. Maybe that's the issue in my case as well? I got Wi-Fi calling, but the phone is unlocked and I got no bloat (except the Google apps).

Quite possibly, I'm not seeing any extra drain than I should be and I'm running the O2U firmware (United Kingdom)
I have WiFi calling and 4G calling too, might be worth flashing this firmware to test if yours is the G960F? There isn't really much bloat, a couple of O2 apps only and you get the option during first boot to install or not install them anyway

Do you know how can I disable the bloatware now that BK Plugin 2 and BK Package Disabler are down?

Package Disabler Pro & PDP engine addon, both on the play store

Well, I found the Package Disabler Pro + after my last reply and installed it. Didn't install the PDP Engine Addon as I hadn't read your reply at the time and the app said the Disabler Pro + worked alone without the need of another plugin.
Automatically disabled around 120 bloatware apps, restored the ones I needed or wanted to use, and disabled a couple more that were carrier specific bloatware. Restarted the phone, charged to 100% and went to sleep after unplugging and setting my alarm.
Woke up this morning after 7 hours of sleep with 99% and a smile on my face. Seems that it was bloatware the culprit of the standby drain, and even my day stamina has been improved, today I've given it a light usage and I'm still at 81% at 6PM with 1hr 24m SOT.
Thanks a lot for your help!
