My T-Mobile USA (standard ROM) Tp2 behaved very strangely earlier today, but seems to have recovered. Anyone had any similar experience?
a) Battery level decreased rapidly, and unit getting very warm
b) Battery Status today plugin showed > 900ma (and sometimes > 1300ma!!) current draw
c) Unit would not charge from my USB port (message that it wasn't providing enough current)
d) I put flight mode on, no appreciable change in behavior with all radios off.
e) Soft reset - no change
f) Task manager didn't show anything using undue amounts of CPU
In the end, I turned it off (completely), and it would then charge normally. Left it like that for two or three hours, and when I turned it back on everything seems to be ok.
I have a lot of software on there, but nothing installed new in the last few days. It's worked perfectly today - best cell phone or PDA I've had since my trusty Phillips Velo...
While this was happening it seemed slightly sluggish, but certainly not locked up. Only 'unusual' thing - yesterday I let the battery get real very low for the first time (left it with the screen on, and an app running). I almost wonder if somehow there's a power management issue recovering from this. Note - it was never completely dead, just very low.
Anyone had anything similar happen? I assume the problem is in the phone, not the battery (otherwise I wouldn't have seen the current draw)

you can try to hard reset and put everything back in...
what i usually do is turn off 3g because it consumes a lot of battery..i'd use wifi as much as possible or edge.
you can try using cleanRam to clean up some excess space on the phone.
not sure about the charge, you might need to restart your PC or reinstall active sync so it can detect the phone.

He's not talking about ActiveSync or not detecting his phone.
However, I notice this behaviour almost all the time (device runs out of battery within one night) but only see those large power consumptions sometimes.
My device cannot be seen by any PC I tried (after first installing Mobile Center) so maybe there's a flaw in some devices?

Yes -sorry I didn't make that clear. Phone was working ok (including activesync) - it's just that it was trying to take too much current from the USB port.
This has only happened once (fingers crossed!). I'm sure it's software (rather than a hardware fault), but I'm puzzled given that the task manager showed minimal CPU usage, and the power drain continued in airplane mode

Your reception is probably bad. The TP2 will basically go insane if the reception is bad enough, I've seen it drain a fully charged battery in under 3 hours if you have push data turned on and there's 0-1 bars of reception. The battery life is quite good when reception is at least a few bars but once it goes below a certain point I've definitely noticed that the phone goes insane and will get noticeably warm in the pocket and basically die within a few hours.
Turning off push data will get you slightly better battery life in this scenario but unfortunately I still found that the battery would still be dead by the time I needed to use it. And it's not a network issue either since I tested it on different networks and compared it to other smartphones dealing with the same terrible reception-this phone definitely uses an insane amount of power when reception is bad, which isn't a problem if you're just transiently going through a bad reception area (probably helps keep the signal from dropping) but if you're spending a few hours in a place with poor reception it will drain insanely quickly.
Thankfully I'm spending my time in places with better reception now-I basically ended up having to turn off the phone if I wanted it to still have power by the end of the day but now it's still nearly full at the end of the day with just moderate reception.
HTC should really change the phone's behavior when there's 0-1 bars-it's nice that it tries to find a network aggressively when it loses a signal but there should be a timeout on it where it should start checking at longer intervals if there's a long period of no signals unless someone's trying to make a call or something. Really useless when you put your phone down for 2 hours in some overly shielded building and when you pick it up to make a call and it's dead. Not to mention uncomfortable when it starts heating up like crazy.
I'm not sure why you still got battery drainage even in airplane mode though but maybe the phone had already gone into whatever insane mode it goes into when the reception gets bad. Maybe it's one of the apps running the background that freaked out as well? I think my battery life was still kinda bad in airplane mode as well, for some reason I had to literally turn the phone off to get it to stop killing the battery.
i get zero bars at work and no reception. i've noticed that at work, my phone gets destroyed and lags like crazy and barely usable. it gets no reception for 8 hrs so its nice to know that other ppl are experiencing this problem and its not just me.
my tilt did this today, was warm to the touch, idled' didn't use it all day 6 hrs idle with signal, battery drained to 50% made a phone call 13 min duration, put the phone down watched a 2 hr show, phone dead.
not from signal/data.
My Tilt2 stock rom appears to have done the exact same thing today. Yesterday it had low battery for the first time ever... then today, it completely died in my pocket while at work (usually I have about 80% battery left at the end of the day). I noticed early this morning that the phone dropped from 100% to 60% about 2 hrs after it was off the charger. The phone felt hot. No programs were running in the background either. When i saw this, i ran cleanram and it still died a few hours later. Reset the phone and charging it now, hopefully this was a one time thing?

I think this might be it. Reception at work is normally really good (there's a tower in our parking lot!) - but I noticed today they are working on it.
The strange thing is that putting it in flight mode did not stop the power drain - to me that just doesn't make sense. However, I'm thinking that when I first did a soft reset, it probably wasn't in flight mode. So, the complete manual power down, followed by the resulting soft-reset into airplane mode) might be what fixed it.
My phone is often in areas of poor coverage (NW CT) - pretty much every day to/from work, and I've not seen this behavior with the TP2 before. Other GSM phones I've had do noticeably use more phone in areas of poor/non existent coverage, but this was a relative melt-down - I did wonder whether I had an internal short.
It's been ok since, and I'll report any future incidents or findings...
Happened to me two times, I figgured the problem was the GPS connection, improper exit from GPS app (AmazeGPS). Can be related to GoogleMaps or other app too. After restart, everything went back to normal.

If that is so, how can we check if the GPS is still running?
I do a reset often, but that won't change a thing...
Besides, when I look, the power consumption often is 'slightly above normal' - 150maH-250maH.
btw: what is considered as normal consumption?
Battery Status plugin
I hate to sound like a fool, but I'm running the stock ATT Rom on my Tilt 2, and I cant find the "Battery Status today plugin" you mentioned. Is that a T-Mobile only thing?
Is there a .cab for it?
To reply to the primary topic though, I've experienced the heat increase/battery drain level thing, but it just started yesterday after I installed a whole bunch of stuff. This weekend I'm planning to hard-reset and load stuff slowly so maybe I can isolate the cause.
I'll post an update if I figure anything out.
FWIW - I've recently been trying to track down a battery drain, too.
For me, though, the drain has correlated with trying out SPB Mobile Shell 3, so that is clearly a likely candidate. However, the drain does seem to be mainly limited to night time.
For example, on Sunday the phone dropped to only around 80% after a full day out and about. However, by Monday morning it was down to 10%.
Similar results on Tuesday night - almost complete drain by the morning.
To see if I could work out what was going on, I installed acbTaskMan yesterday, and set it to log CPU overnight (it periodically logs CPU usage, power drain and the top three CPU users).
Unfortunately, there isn't any *obvious* candidate:
Microsoft "My Phone" kicked in for a couple of minutes and used quite a lot of power (max of 493ma). However, this dropped off once "My Phone" had done its stuff.
A lot of the time, its actually acbTaskMan which is the top user of CPU (probably unsurprising, given it is monitoring and logging).
There does seem to be a bit of residual network traffic - every five minutes (or so) there are a few UDP and TCP packets being sent.
Overall, the average reported power usage was about 113ma (with the max being 493 and the min being 5!). However, the reporting period seems a little odd - most of the time it reports every 5 seconds, but there are a few periods earlier in the night where there are gaps of up to 5 minutes.
What would people generally expect the average power usage to be when on standby?
FWIW The comments in this thread about low signal could certainly be relevant. I do have pretty low signal at home and I did leave the phone in a slightly different place last night (where it could have had a better signal than the two nights before).
My current hypothesis is that
Something in Mobile Shell is causing the network connection to keep alive all night (or is at least turning it on every five minutes).
This coupled with poor coverage in my house is hosing the battery. During the day, with good coverage, the network traffic isn't causing as much of a problem.

you might want to try this.
Under MyPhone, disable the Current Location.
Under HTC Settings->Location, disable all the location information.
See whether this helps?
Thanks - this is a good idea.
However, I think I may have uncovered a more fundamental (and dumb) cause. Somehow (probably user error, but I'd like to think some nefarious impact of installing the SPb stuff), my "peak" times for Activesync had been changed from 8am to 6:30pm, to 8pm to 6:30pm. This completely explains why my connection kicked in every 5 minutes overnight (as this is what my "peak" exchange sync is set to).
Having fixed that (!) I'll see whether my power usage is miraculously better tonight! If not, I'll give the location stuff a go too!
Ed
Checking mail all night is not a good idea!
Ahh yes - much better now. I went to bed at 80% battery and woke up at 70%.
The task manager log has logged far fewer points (only 300 logs over 7.5 hours, as opposed to the 5400 that I'd expect if it were logging every 5s), which I guess indicates that most of the night my phone was in "deep standby", or whatever one might call it.
FWIW I certainly recommend acbTaskMan as the logs it produces are very handy to spot what is going on for this kind of thing. For example, even in a low battery drain night I can spot exactly when various services are using the network (e.g. checking mail, Google Maps updating its latitude stuff, etc.)

I noticed somethin strange last night.
The battery was still for 63% full when I turned the device off (Yes, really turned it off!) and still next morning the battery was completely empty!
Now how is that possible? I do have two batteries, which do exactly the same, so I could test this with the other one, but this seems to be seriously wrong!
I had a similar problem with Sprint. after several trial errors, I traced the problem to the Verizon radio (2.23) I used after SIM unlocking. I went back to sprint 1.96 and voila. Since then now I have moved to Sprint 2.32WU and it works even better.
Another battery saver is this trick "disconnect network when idle for 1 min timeout":

Had same thing happen...new tilt (1 month old) got hot and drained battery in 3 hrs with no use! I believe its a GPS program such as googlemaps or Trapster that caused it. A soft reset and im golden. Hate having to soft reset all the time
see this often, almost always because gps is running and did not shutdown when the program using the gps was closed. Chartcross GPS test will show you if the gps is running or not and usually will allow you to exit, and stop the gps induced battery drain. I have gotten in the habit of doing soft reset after using tomtom or google maps, to ensure that GPS is off.
At least for at&t devices, gps is the culprit for huge battery drain, hot to the touch. I will add that little or no signal to the phone will do the same thing. When I am in marginal coverage area, I turn off 3G and that seems to stop the excessive drain and heat build up due to low signal strength.
Not straightforward, for sure and one has to pay attention to the device, or when you need it most, the battery is done.
Today was my first day at work since i got my Desire on Sat. So it was the day without regular charging.
Firstly, reception was poor as compared to what i was getting with Touch Pro 2. Same network (Orange), same place, less signal bars and less 3G coverage.
Secondly, unplugged phone 7 o'clock this morning, 100% charged. All day only had time for couple of calls (10-15mins). Used internet (3G when available) for max 20-30mins. Tried couple of games for 15-20 mins and at 7 o'clock at night, the battery was 15%. This is not a heavy use by my standards. Used to do a lot more on Touch Pro2 and battery used to last 2-3days. (I know the capaciy difference btw Desire and TP2 battery but still, Desire should last atleat > 24hours)
Not sure if all these issues are related to Orange ROM/Radio. Will we (on Orange) get OTA firmware update like T-mobile, which has apparently improved their battery life? If not then ...... :-(. Not satisfied with the battery life. Shame it is such a good phone but battery life and signal strength is putting me off.
Whats the fun if you have a "superphone" in your pocket but cannot use it to its full potential due to these two isuues.
Mine was the same,
But after a weeks worth of usage, its now reasonable, IE 18 hours between charges,
Fon22
I totally agree, there are other posts telling us to turn off or reduce all sorts of settings, its ridiculous that you would have to run any phone at less than its full potential just to compensate for a poor battery.
Sure you could buy a second battery but if that was necessary then they should put two in the box
If you leave gps on then you are asking for trouble, a lesser extent wifi. Having a toggle on off isn't such a hardship though. Poor signal hammers the battery too.
I easily last the working day (7-7) with an hour of music and 2 hours surfing and a smattering of calls and texts.

Come on guys, if you have a laptop, and you turn on bluetooth, wi-fi, play some games etc, it WILL run the battery down faster. It's just common sense. Just because this phone does heaps of things, dosn't mean it will last forever. As phones get more features, they are getting worse battery life - in general. And android is a data centric device, I would get used to it, or simply turn off some synching features if you need to get through more than half a day. Or perhaps get a spare battery etc.
Just out of curiosity did you have your previous phone to constantly sync throughout the day for time, email, google account, marketplace updates, location, weather using gps, 3g, hsdpa, accelerometer etc? Remember some of these connect are activated every 5 mins or so. Will make it worse if you have poor reception. COMMON SENSE PPL!
My issue is that even after the T-Mobile update, last night I charged phone on this time and it would only get to 98% again. Then drop down quickly.
If I charge it off, It seems to be ok (although I will test this again.)
Frustrating.
My battery life is woeful (TMo uk, updated firmware). I've been trying to figure it out using Juice Plotter to record power usage. Basically, whatever I'm doing, if it's on the battery falls off a cliff - I'd say 10% per 30m and my first impression is that it makes little difference whether networking is enabled or not. This makes little sense to me, I've always found in the past that 3G is just about the most power intensive activity on the smartphone, but it's consistent with some experiences I had flashing roms on my Blackstone - some of them would just run the battery down, others would go for ages. One hypothesis is that when a phone is in that kind of "sick" power state, the drain is not really related to which facilities you're using, but something deeper - perhaps the CPU is running full throttle all the time, or something else. I have no idea what's going on right now but I know I have an unusable phone which lasts half the time my Blackstone did with heavier use. I think many others have the same problem and I wonder if there's a bad batch. Bad news if so as we'd have trouble proving it and getting exchanges.
My next step I think will be to hard reset and run it in a very basic mode for a while, maybe some of the apps are causing it.
I'm also finding out that battery life improves dramatically after the 5th 6th charge. When I first got my Desire I could barely make it through the day, after properly charging and letting it discharge all the way to 10-15% now I get 18-20h of battery life with wi-fi on non stop (but with the setting to to turn itself off after 15mins of inactivity).
I was very worried about this when I first got the phone, but now it's starting to be better and better at battery life. I know my demands from a smartphone when I buy it and if a phone get's me through the day I'm OK with that, plus I have chargers at home, in my car, at work, so it's not a problem
I've got one of the very first batch of T-mobile Desires that were shipped on 26th March. It has been updated with the T-mobile 1.15.110.11 patch.
I last charged it on Saturday afternoon. I've only had to start charging it again this morning Tuesday. I've been making a few calls, probably 10-15 minutes total. A few texts. Browsing with G and 3G, maybe a few of hours worth in total. Little bit of Bluetoothing, though that's only a couple of minutes worth. I've had it down the pub a few hours where the T-mobile signal isn't brilliant, so it will have been doing a little "shouting" to find and communicate with the nearest T-mobile mast.
But that means it's lasted a good 66 hours admittedly with fairly moderate use. GPS, Wifi and Bluetooth are turned off unless needed. And it's not regularly Syncing with Facebook, Twitter and all that stuff. The only regular syncing is the weather.
Not sure if these are bugs with some hardware/software or standard functionality with your usages. I'm getting excellent battery life with my usage patterns/settings and far happier with this than with any of my previous devices, since this adds an exorbitant amount of power-draining functionality and flexibility over them too.
- Heaviest use is netting 28-33 hours.
- Typical use is getting minimum 3-3.5 days.
- Light use (also the norm for me me) lasted 5.5-6 days.
- Basic inconsistent call/message/email/net/stocks/news/stop watch/GPS/ compass/notepad/office/weather/ vid/pic/audio throughout the day kept the battery at 84% after 24 hours. 3G off, using WiFi. I don't keep any but the needy apps/settings running BTW.
- Charges to 100% always and stays up there consistently as expected.
However there is a pertinent aspect yet unmentioned;
Biggest difference between my usage and the typical internet crowd is that I don't use or bother with "social networking" (Facebook, MySpace, Twitter, etc) or its likes nor do I play any games on this (hence sync with such apps is off and any updates are set to manual). However rss feeds, e-mail and IMs with close ones I do use during the day when I have spare minutes.

Same situation as mine there.

I'm deffo leaning now that there are faulty batteries out there causing the problem. I can get good life if I can get the battery to charge properly. but when it doesn't battery lasts hardly half a day. I don't use any apps that require automatic updates (all manual or off). But net on drains it very quickly (if I leave data on). Faulty Batteries I feel.
My Desire has a better ability to hang on to a weak signal than my other phones. I am on T-mobile. Battery life is adeqaute, in that, I can get through a day of use before a charge is needed. Will switch-off GPS and see what happens -I never had GPS on all the time on my other Smartphones.
Coming from a G1 that could barely make it through the day on standby this phone seems pretty good.
I got mine last friday it has just come off of it's third charge. I charged it for 3 hours when I got it, ran it right down >10% then left to charge up fully again.
I installed JuiceDefender and bought the UltimateJuice upgrade as soon as I got the phone.
Day 2 (with JuiceDefender) - battery lasted 13h27m, thats with WiFi, phone calls, MMS, 3g, internet browsing/showing it off to mates in the pub and then listening to an album on spotify in the car.
Considering this is a new battery and it still needs several charges before it is working at full capacity, I think that is pretty good for a smart phone! It can only get better, right?
JuiceDefender - I can't recommend this app enough, I don't want to mess about with Task Killers (that don't really save battery), I don't want to stop stuff syncing (because thats the whole point of this phone) but I want to optimize my battery life to get me through the day and this app does it so well!
I've currently got it setup to turn 2g/3g off when in standby but set to turn data back on every 5mins for 30s to allow apps to sync. You can specify a longer interval which will obviously save more battery over the course of a day. The phone connects back to a 2/3g connection so quick when you bring it out of standby so your not waiting around to get back online.
Switch on WiFi at known locations - I have this setup because at home, 3g signal is a bit patchy and it probably uses more battery constantly trying to get a 3g signal all the time, than it does if it is just connected to WiFi.
Turn data off between 2am-8am while I am sleeping.
Turn data off when battery is below 15% - with my G1 it would hit 15% just as I'd be heading home on the train in the evening, so I'd turn data off just so I could send a few texts or so I had just enough battery to make a call. So I figured I might as well use that last 15% battery for basic phone operation and give me enough battery to get home! I probably don't need this with the Desire though.
Any one else using JuiceDefender?

WOW, can I have your battery please ...
What did u do to get this powerhouse. Was it weaker in the begining and got better with charges or was it like this from the begining?
I dont use GPS at all. Only for navigation, when in car and then it is on charge. Normal day.. no gps, no auto data connection - do it manually when internet connecttion is neede. But battery doesn't last a day, merely 12-14 hours. Charged 3 times yet, only 3 days old Desire.
I cant find juice defender in the market?
When I first got my Hero I remember my battery life being terrible, most of it was down to fiddling all the time, however over time my usage changed and the battery had been charged a lot the life was a lot better. Also there were a number of radio upgrades installed, which probably helped.
Since I've got my Desire, the "desire" to fiddle hasn't stopped and I feel as if I'm in the same situation as I was with the Hero.
My opinion is that over time the battery life will be better, as with the Hero.

Yes both Ultimate Juice and Juice Defender are in the Market.
Juice defender was missing for me a couple of hours ago. But actually, when I installed it thinkgs started to go wrong for me. May be a coincidence, or may be a conflict with some other sw.
Following shocking power drain, I have hard reset, and left it with nothing syncing and all networking disabled. As you'd expect, battery level is barely falling in standby. Now to start adding things back in and see what efects it has. First step is to spend 30 mins browsing over 3g, previously this would take out 10% of my battery.

Hey folks,
for those who sufferred from the data outage today, do you observe a severe battery drain in 4G mode?
Even the phone is idle, it is consuming 8-10% per hour, while usually at this time of the day, I will see a straight line if my phone is sitting at the same area idling...
What area is the outage in? The most probable cause for your battery drain is the radio trying to search for signal that isn't there.

One of the biggest problem is when modern day phones keep looking for a 4G/3G signal in a poor reception area.
Either by forcing your phone to use 3G/2G it should reduce the drain

I've done some tests; my PIL's live in a cellular black hole, and drain was phenomenal, no way around it. If I'm spending a significant amount of time there I revert to WiFi and/or turn off data. You'd likely observe some nasty user and kernel wakelocks if you have BBS installed.
I'm in western PA and mine has been going nuts all day trying to pick up 4G, when its normally not a problem. Even after the outages "cleared up", it has been struggling.
yeah.. the problem was, even I turned off mobile data, the drain is still ON. seems to be a problem in celluar signal etc itself.
Similar thing happens when I was at home, one particular place (between two pillows in my bed), the drainage was crazy overnight. even I have wifi on.
Thats because its still an "outage".
The ehrpd network is down and turned off. Devices are now switching between Rev A. and LTE. Expect longer transitions.
Verizon needs to seriously dedicate more time to fixing these LTE issues, but hey how can we complain, they were the "first".
So my excessive battery drain started the other day when the LTE network is down. (NOTE:I am not in an LTE area, and I do not have LTE enabled)
My battery drain is approximately 10%/hour, if the phone screen is off (ie the phone is powered on, but in 'standby' or 'sleep'). If it is doing something (say, playing music to me while I work, which I normally do everyday), it drains even quicker (roughly 15% to 20%/hour). This is much worse than normal.
While I can't say that I'm seeing any 'app usage' that is much higher than normal (mediaserver and com.mixzing.basic [my music player] are right below my screen usage), I can say that suddenly my CPU state percentage (seen using CPUspy V0.4.0) is 70% in 350 MHz, 26% in deep sleep, and the last 4% broken up between the 3 higher speed states. This is disturbing, as previously 350 MHz was not that high, normally I was seeing a much higher deep sleep percentage (over a 24 hour period...this is over 37hours atm).
Something has changed, and I fear it's something in conjunction with Verizon. I haven't changed anything with my phone in this time period, no 'new' rom, nothing. I've been running the leaked V4.0.4 stock ROM (rooted of course) for approximately 2 weeks now. My previous battery time was acceptable. This is not, since I cannot even go from breakfast to lunch now without having my phone tethered to a charger.
Any ideas? I've searched, and nothing else really matches this except perhaps this thread. It's not an exchange problem since I don't have exchange (as others have posted previously about that in other threads, I use gmail for my email).
AT&T - 4.1.2, unrooted
I've been trying to figure out what's going on with my battery life overnight. Battery life is good through the day, drops much faster overnight. I've factory reset probably half a dozen times, slowly added apps back, etc. At this point the only thing I can point to is the mobile network signal. Here's my story from yesterday:
Fresh charge to 100% at 9:00 am at work. Very minimal use (to rule out the screen use), even had my google account sync off. At 4:00 pm (7 hours) the battery dropped to 97%, or .4%/hour (excellent). My mobile network signal was constant, according to my battery graph.
I turned my Google accounts on to sync automatically at 4:00, and over the next 6 hours my battery dropped to 89% (1.3%/hour). I could still live with this usage, but I noticed my mobile network went black around 8:30 pm, and see the graph dip a little with it.
So I let the phone go overnight and checked it at 6:00 this morning (8 hours) - battery dropped 22% (2.8%/hour - not acceptable). No other settings were changed, but notice the mobile network being black:
But did I actually lose the mobile connection? GSam doesn't show that I did. And looking at my wife and daughter's S2 (my N2 sat right next to my wife's S2 overnight), their mobile signal is full/good all through the night.
So what the heck does all of this mean? I've watched this happen over different nights - occasionally it doesn't through. Do I have a lemon with a bad radio, or is it the combination of the N2 and AT&T in my location that I'm just going to have to live with? I don't understand this band talk enough - my sim is coded to LTE, but I'm pretty sure we're not in an LTE area. Looking at the graphs, I don't know that that matters though - it looks like it's something with the phone signal.
I have about a week left in my return window (bought it outright thru Amazon). Should I just exchange it? Any other troubleshooting ideas?

hey there. ive had my p6p for only a few weeks. battery life has been poor since i got it, but worse since the march update. i noticed when i look in settings under battery and battery usage and then past 24 hours i see mobile network usage at 70%. i haven't left my house in over a week and ive been on wifi the whole time. isn't that weird that the mobile network would be in use so much? i looked under network and the sim and by default roaming was toggled on. i turned that off and switched my preferred network to lte instead of 5g. a day later, still not left the house and i see mobile network at 54%, still high. i haven't even made one call on this phone in days. im on t-mobile if that matters and seem to have good reception in my home. any ideas or settings i could look at? thanks for any replies.
Go to developer settings and disable "Mobile data always on" option, as well as you can disable the 2g always on for emergency calls from the wifi&network settings. That helped me.

You're welcome
Dont know whats wrong with my p6p. Was one of the users who had zero problems since december, switched then to 12.1 beta. Now im on QPR 1.1 and since QPR 1.0 my battery drains like crazy, and even with the slightest of usage while using 4G/wifi it gets way hotter then before and you can see the battery % falling like a waterfall. Checked ofc all the settings, nothing changed. All apps are the same, nothing new. With Dec Firmware i was at ~50% at the end of the day, now im below 10%.
Im a die hard android boy, but for me thats crazy how unstable the whole "system" is. You change nothing app/usage wise, and you just loose nearly 40% of battery capacity.

I personally hate the battery life on this phone. I charged it to 85% earlier and was texting a buddy of mine for a bit, and my phone was super warm for no reason and I lost like 20% just from that. It doesn't make much sense to me how the power is bad that if I do light tasks it just goes to crap. I hope the next phone is better.
Personally, forget the Mobile Network standby figure is just misleading.
On the original firmware mine said 3-7% and I would charge to 80% and then 24 hours later would have around 30% left. By the February release the standby figure was showing 40% but battery life exactly the same. With the March release it is ready 50%+ but again the battery life is still pretty much the same (couple of % more but that is because I moved to a dual sim setup).
Don't disagree that some are having battery issues, but don't go chasing the Mobile Standby number as it is likely a complete red herring and your issue is elsewhere.
yeah i noticed that too. Im no way focused on that % mobile standby. Im feeling the noticable higher temp on the device.

There are reports that the older 5G modem is at least part of the problem, so I would not dismiss it. The fact that so many disable 5G, 2G, or other mobile services and report better battery life is kind of telling, too.
I think that the March drop has improved my battery life a bit, however. Not great, but it lasts through the day.
My battery life has definitely decreased since updating to march build. My usage hasn't changed, but before, I went to bed with ~15% left, now I often need to recharge at ~22:00 whenever I want to use my phone before sleep. Temps also seem to be slightly worse. I sometimes notice the phone getting warm, which did not happen before.
On a plus side, I have no more connection problems at home since updating to March build (I can get SMS/calls again in my home office), so that's a trade-off I am ok with, even though I don't like it.
mobile network is definitely my problem. since i stay home most days, working from home and not needing to go out, i turned on airplane mode and then enabled wifi and bt. i get calls from wifi thru tmobile and suddenly my battery life is great. 24 hours after charging with light use i had 89% battery remaining. i believe overnight i had lost 1%. i plan on leaving it in airplane mode till i go out. i get my notifications and calls and have great battery life this way.
I've noticed a steep decline in my battery life as well since the March update. Mobile network appears to be the culprit. Verizon user here, on an old GUDP.

I find it sad we have to go through such hoops to get our battery life adequate enough for our standards, when it should be this way out of the box. I hope the next pixel phone improves upon this, and if it does even in the smallest way I'll be sure to trade my device in.
I found the "issue" for my drain/heat problem:
I discovered yesterday evening, that i was enlisted in the play service beta program. Opted out of it, cleared cache/data too. Figured then out, that my gpay cards went missing, added them back in 5 mins, no prob. Then i saw, that all my "battery setting per app" where on "optimized", not on restrict. Today i unplugged at 08.30 and till now after a 20min call and twitter/instagram usage, im still at 96% with absolutey NO HEAT!
Config:
Play Services 21.24.23
Carrier Services 98.0.435052141
Play Store 29.8.13-21[0]
S3B1.220218.006
Hope, that this maybe help someone

Weirdly mine has noticeably got better, i am ending the day with 20 or 30% more battery left than i was before the march update.
