[Q] Desire HD battery life question before I buy

Hi,
I'm planning on buying a Desire HD, but just curious about battery life before I lay down a grand on it.
At the moment I have an HTC Hero, when they were in their heyday many people complained about the short life on them. I can get 2 days out of mine, with syncing over wifi enabled the whole time. I put the complaints down to people with background apps sucking CPU or too much twitter/facebook/whatever crap syncing as well.
Now most of the reports of poor Desire HD battery I life are from people on their first charge (who clearly don't understand the characteristics of Li-ion batteries), people who expect to be able to thrash the phone all day with the screen on without it dying and generally people who just don't sound like they know what they're talking about.
I know there are two bugs which peg the CPU at 100%, the one fixed by having debugging on and the calendar bug, which sounds like it can be fixed by clearing calendar data or leaving syncing off. I think these were affecting some of the people who were complaining about the short battery life.
So my question for Desire HD owners is, can you last at least 6 am till 10 pm with a bit of use (something like 10 min browsing, 20 min IM, email syncing all day, 1 hr music, 20 min calls) without it dying? Currently my Hero does this fine and a full day without a charge is a requirement for me.
Thanks.

Yes, if you set it up correctly. From your post it sounds like you know what your doing when setting it up.

Before i tried the battery calibration i was getting from 8am to 9pm with moderate usage. TBH i was put off by using it as I thought it would just die on me too soon.
After the calibration (search forum for it) i got from 8am to 4pm the following day where the 15% warning hit. So do the calibration and you'll be as happy as i now am with it. I never got my iPhone 4 to last that long!

Thanks for the info guys, exactly what I wanted to hear!

I haven't taken any precautions to save battery life and I am getting 25-26 hours on a full charge...and now having had the phone for 2-3 weeks it seems to be getting even better!! I've been getting 36 hours out of a full charge these past 3 days.
I do not turn wifi off. I have screen brightness on auto. Syncing lots of stuff hourly (even weather!). I use 3g when I go out but this is about 2-3 hours tops on week days cause I have wifi everywhere i go. battery life has never been an issue for me and I use my phone frequently...play games for 20-30 mins. watch videos via. skynews, listen to some music etc. etc.
As for the bugs...I do not have usb debugging turned on and I have never had the /INIT problem...perhaps it was fixed in the last update? and the calender bug...never had that problem either and I use my calander with google calander, facebook, holidays and person agenda.

I think you'll easily last a day with the usage you mention. As a rule, I think you normally get up to 4 hours display on usage off a charge (browsing, messaging, watching vids etc).
I'm travelling from Ireland to NZ on Monday, which will equate to 36 hours travelling with probably no access to a charge, and lots of time spent sitting around using my dhd. There's no way the phone will last right through, so have bought a 5000mAh USB battery pack for £20.

I'm currently at 22 hours and still at 42%.

I get 2 to 4 hours depending on useage from full charge. 8 - 9 hours if left on standby and not used for anything.

Well...I think I have had similar results....
flash one of the custom roms, with one of the OCUV kernels and setting max. speed to one of the UV speeds (mine is set to 1.1 Ghz which is UV 50mV), also setup useful profiles in Setcpu (I have set screen-off to use max 384 mhz - which does cause a 1-3 sec lag when screen is on again) and <20% battery etc...
of course, if you play heavily with your dhd you will not get these results, so you can put wifi on with this , but need to think of what you want to do, because using your DHD for 2 days, does require limited screen usage (imho, this uses a lot of battery)

8-9 hours on standby???????????
even 2-4 hours whilst using it is terrible!!! When I got my HD and unpacked it I didn't put it down after a full charge and I got 8 and a half hours with non-stop heavy use.
I think you have a faulty battery!!

I too moved from a Hero to a DHD and I can say that with similar usage, the DHD loses to the Hero by a decent margin..maybe u might get a couple of hours less of usage compared to the Hero but the difference isn't very drastic
Moreover on the Hero I'm using CM6.1 Froyo overclocked and the DHD is on Sense, so logically speaking the Hero should get slightly better battery life on CM6.1 compared to Sense. I'm sure after rooting and flashing CM6.1 and undervolting/underclock the DHD, i'd get better battery life because the DHD is like much much faster than the Hero, so I'm sure even if i underclock it, it'll still be super fast.

The battery is 'fine' i'm using current widget to track and its performing to around 1100 mah which is not too far below spec. The problem is the current draw. In use i'm drawing 500 to 800 mA and in standby around 80 to 300 mA. These figures are consistent with the battery life I'm seeing and the battery working close to spec (1230mAh i think?)
There are lots of bundled apps like Maps running all the time in standby drawing current and I haven't yet figured out how to stop them. Stopping them with task manager just sees them restart with even bigger current draw.

Something is definitely wrong (as I'm sure you're aware) with only 9 hours on standby.
Out of interest, remove ALL widgets and see what difference it makes. Also, give us an example of what processes are running?
I would get rid of all task killers and also anything monitoring your system. Those themselves can draw more than you think.

wow well I'm no battery expert but it really sounds like something is not right there. I don't have any battery drain from apps in standby and I do use maps.
I got 1 day and 16 hours from a full charge today (just put it back on charge now).
Thats with wifi on for 31 hours (always on, doesnt sleep when the screen locks), 1 hour and 24 mins of talk time and the screen on for 4 hours and 5 mins.

thats definitely wrong somehow.. should never drain that much, perhaps it is because you let currentwidget drain it all the time
(na dont know why it is like that but it definitely is way too high)

official firmware, medium screen brightness, default sync widgets
heavy use: 12-15 hours
light use: 24 to 36 hours
this is how its been for me ever since the battery calibrated, needs around a week or use the battery calibration trick

I too have just moved from a Hero (running VillainRom 12) to the DHD (stock Sense over FroYo) and even though I have only had it a week, the battery easily lasts a whole day with the moderate use you describe. Unless I get stuck into a session of " Angry Birds ", which seems to kill the battery pretty fast. But ABs had the same affect on my Hero. Constant screen time on that beautiful 4.3" display sucks the battery. I find the same thing when using the DHD as an in-car gps. The warmth of the back of the case is testament to how much energy has been expended. So I connect to the car charger now. I have also bought a portable backup battery (plugs into the microUSB) just in case.
I don't regret spending NZD1000 on the DHD. My son is looking forward to inheriting the Hero.

Well I charged it up overnight when I got it, my first full day was today and I got 7 am till 8:30 pm using it almost constantly (quiet day at work). I don't know how people can run them flat a day with normal use. And I know it'll improve a lot after a few charge cycles.
It doesn't look like it's going to be much worse than my Hero.

Thanks for all the advice. I uninstalled all widgets and it improved a little. But still things like maps/maps sync were constantly burning juice and no way of stopping them running.
I installed Launcher Pro and can report that my battery life has approximately doubled. Typically i was getting 4 - 6 hrs use and sometimes only 2 (light use). Now getting between 8 and 12 hours of fairly heavy use. Its still not up to some of the figures others are reporting but Launcher Pro has helped a lot as all those constantly running apps that were draining my battery just dont start themselves up any more!

[Q] Battery life

What do you guys think about the battery life on this device?
Speaking by my own experience it's pretty okey - not on the upper front of the existing devices, but neither on the lower front. It's pretty mediocre, right?
But that doesn't make me satisfied, I believe it's to short.

By playing a wifi conected game, mine is up to 5-6h I think. Otherwise, It's like yours, 12h.

Hum... With regular usage (about 30min games a day + 2h music + normal stuff like calls and SMS, including about 1,5h of Wi-fi on) mine lasts about 36h, if playing games all the time, around 10-12h. But well, it's underclocked for "screen off", so even when the music is playing, the CPU is only running at 368MHz.
I'm quite happy with this stats so I have nothing to complain.

What kernel are you using ? and are you using the stock Rom ?

No, I'm not using the stock ROM. I'm using TuxBrothers' EUR XXLA2 ROM OC which comes with this kernel. Of course the fact that I set low brightness also matters a lot since the display is what consumes most energy anyway. Right now it has been on for 29 hours and has 28% battery left.

for me i think the battery life is fair enough, my phone is up for 19 hours w/ 40% left, internet, games, usual stuff, underclock on screen off, overclock @ 1800 sometimes , and w/ low brightness, im using cowithgun's OC rom

I find it amazing compared to my SGS2.
My wife's W, with low usage, no data on but WiFi always on, running standard Juice Defender will get 4+ days if no app has gone runaway or otherwise.
Very stock on latest XEU standard firmware.

Well I might agree with you that it's more than okey. In fact, it's really good compared to the other phones. - Changed my opinion about this subject, hehe.

Does anyone know if this new myth about battery draining too fast on KEZRA V4 is true? I feel it draining a little fast too, but I'm not sure.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the OnePlus 3 before depleting the battery.

Sounds great so far, knowing that the battery normally becomes better after 2-3 days of charging I hope that we will reach even better SOTs

I hpe for at least 4-5 sot with wifi and normal usage and 3.5 hrs for mobile data.

Mobile data 3g

SOT really depends on usage, and whilst I was one like many here that is obsessed with SOT, I've started to just use phones without really worrying about it. Plus Dash charge is a great addition (aside from having to carry the charger with you).

Used a few apps, specially Snapchat and Whatsapp. Got a screen on time of 3.5 hrs on 4G. Decent yeah. OPO had a tad bit better.

What's the stand by?

I bought it on the launch day and conducted the test the next day after a full cycle. At precisely 5 pm I unplugged the device, at 100%, Connected to wifi with brightness at 25%, with auto brightness off. The phone was at 3% the next day at 4 pm. I got about 5 hours and 15 minutes of screen on time, moderately heavy usage, the phone only lost 6% overnight. Made 15 minutes worth of phone calls, light gaming, lots of browsing and video watching. And some apps with location as well. My previous phone was a oneplus one and for my usage, it seems to be giving me better battery life.

I'm soo ****ing tempted to send my nexus 5x back and get the op3. 400 bucks is a steal with those specs. Also your SOT looks good. Are you using a dark theme and a dark wallpaper or not? From what I've read it comes prerooted?

Nope. Actually refrained from using the dark theme to see how well the battery does. And my wallpaper is the default never settle wallpaper. And no, it doesn't come pre-rooted.

Thanks for the info. Rooting that thing shouldn't be too hard anyway. Wonder how much battery you can sqeeze out with a dark theme / wallpaper? Haven't used an oled screen in years, though. Even more tempted now.

Time on: 7h 2m 41s
Computer power use: 534 mAh
I'll PM the Droplr link for the battery stats and SoT screens
I've using the following:
Dark Mode active throughout
Night Mode active throughout [ I REALLY REALLY LOVED IT, so I keep it on all the time.]
Apps used - Gmail, Excel, Word, Dropbox, Apple Music, Pocketcasts, Fenix, Messenger and Whatsapp.
Data usage is split over LTE and WiFi.
Battery was at 5% as I post this
If there is any other stat you'd like to see let me know

I'm getting exactly 5 hrs of sit for the last 2 charge cycles. Completely on wifi. No sim cards for now and moderate usage with low to no gaming.

9-12 hours depending on the workload and brightness. I easily get a day of use out of the device despite SOT. On top of that, %90 of the time I get 2 days without any issues.

Are you all sure that SOT isn't calculated also while displaying fingerprint area? I didn't test it yet, but it probably also counts sot, so the displayed parameter may show bs.

hmm I don't know, could be.
I used chrome a lot but not sure if it adds up to 7h. I mainly used the phone in bed with lights turned off so the brightness was at lowest setting the most of the time...
I might disable the fingerprint display if thats possible an post another screenshot.
I disabled some sensors with an xposed module and have the feeling that the battery lasts a bit longer since that.
Can give u a list of disabled sensors if you are interested.

Pretty impressed with battery life. And that was with heavy usage : installation of a lot of apps/mods, downloads through games, videos (especially 1h under direct sunlight).
I know it's not representative of a normal day because of the quarantine but I found it really good.

Can anyone else post screenshots? In the YouTube reviews they indicate very different battery consumption among them. 5:30 some, others 8:30

Will post more screenshots after more usage...

Battery life and charging cycle question
Hey Buddy,
May I ask how do you charge your OnePlus 8 phone? All the way to 100% or less? Do you keep it charging on even if its at 100?

Slightly over 4 hours of SOT with 50% battery left.
Impressive and slightly better than what I was getting on my 8 Pro.

Not bad. I'm also using xXx Magisk and ElementalX Kernel.

It depends on which apps you have installed and how you use them. Therefore, results will vary from person to person. To give you some guidelines, this is what I do:
I use GPS and location services sparingly instead of leaving them on
Google app and Google Assistant are disabled, along with some Google analytics
I use a Chromium-based web browser, such as Kiwi instead of Chrome itself
I debloat unused apps that would otherwise just sit there, wasting space
I typically charge the phone to full while it's off and uninterrupted
Touchboost is disabled
Hope that helps.

Thanks a lot. I took some of your tips without impacting what I expect from the phone and it made quite a difference. I had too many apps that I was simply not using. And some applications that were polling my location too much for no reason. I'm also using dark mode as I'm actually enjoying it. I almost didn't change anything but it really shows that if you do some minor tweaks and remove aps you're not using you end up with enough battery to last a full day comfortably.
Really surprised. Attaching my new SOT.
This was a more demanding usage of the phone than my previous post but surprisingly I got 30% more battery then before.
And this while playing COD for almost half an hour.:victory:

SoT is just pefect. And don't worry it's the same everywhere, look :

I think something wrong is going on,poor SOT,never had I pass 5.5 hours of SOT.

Not the longest SOT but I can easily stay multiple days on one charge when using my phone 2-3 hours a day. The flat parts in the plot are the nights when my phone was on airplane mode.
I also had some pretty good experiences while using my phone as a hotspot. This used to drain the batteries of my previous phones quickly but with the OP8 I can easily share connection 2-3 hours and still have the battery last me at least for the day. (Not included in the screenshot)

One plus 8
I get abt 10 hrs

I get abt 10 hrs

My last post was quite poor in infos so I'll detail more this time. Using it one day, you can have up to 10h SoT, using it throughout the days will give you around 8 hours SoT.
I've done two things: used my phone for two days of normal use (at home, playing videogames for about 2h a day because I had no friends to hang out with :crying and got three days of lite use (1h gaming per day or less because I had friends this time :victory, 7h SoT
To sum up: using it over the days will reduce SoT, but overall the battery is really good
Here some pics :

Double post

I dont know if it is normal, or not. But forexample, i chatge phone OP8 full, and i use it, lets say until 50% of battery, then i connect phone to PC to transfer some files. and if i check after battery it said that it is full charged 5 min before, and it stay 50%
