[Q] Dell 7840 Battery Life with Lollipop - Dell Venue

OK I know this has been an issue with many devices since lollipop release , problem is most of the other devices doing a full wipe and cache fix the problem or maybe they get latest firmware updates, something I don't plan on getting from Dell anytime soon =\
Thing is my venue pro with kit kat had a battery life of around 3 days with moderate use since lollipop my battery have been draining even without using the device I notice my Android OS is 60%+ most of the time on battery consumption. Also it takes a lot longer to charge, sometimes I leave it overnight and when I wake up is not charged or sometimes it will just stay at the same percent even after few hours connected to the power.
I already did a full wipe and cache 3 times, anyone else with this issue and found a possible solution?
thank you.

yeah this is the only thing that makes me regret buying this tablet , the community is so low can hardly get an answer anywhere even from dell itself, doesn't even have his own forum space.. bad choice of naming and very poor effort marketing this otherwise awesome device!

I have no experience with battery drain/slow charging with 4 devices upgraded to lollipop. 2012 nexus 7 (1st) fully recovery with official image, LG G2 with stock upgrade, venue 7840 with stock upgrade and LG Volt flashed CM12 from 4.4KK.
For stock upgrade, the key step is back to fully unroot status and receive official OTA and do a full factory reset, which wiped out all data and cache (including all apps). And if you prefer root, then root the device from a total clean start.
The battery with my 7840 is not the best, but still great. Usually, the drain of standby over the night (~8hrs) is ~5% or less with wifi on. And moderate daily usage (actually about 2hrs use during the evening) consumes approx. 30% battery. wakeup monitor shows only 2% of time the device is awake. This is greater than my nexus 7.
The only issue I have with 7840 is my device is a refurb one, so the battery drain is not linear, for first 60%-70% it drains linear, but after 30% left, it drains faster. But I'm feeling ok with that.

That is true. I agree with you about this tablet.
Many people choose certain brand or model based on the community support, like nexus and galaxy devices. That is some research should be done before purchase.
However, certain common Android tricks or tips are working with all devices, like what I mentioned in previous thread to upgrade with stock update. Do not regret, it is actually a nice tablet though.

thank you for your reply
yes its true I own 2 note tablets and a nexus myself. I usually don't buy anything from dell but I had hopes for their "bezel less" products XPS 13 and tablets , they still are great and one of the best looking imo just need to get more noticeable to get more community support.

Greenify fixed most of my issues with the battery life on the tablet.

How to switch Dell 7840 to quick charging (AC mode)

I have the Dell Venue 8 7000 (7840) and it looks like when I plug in the micro USB cord (which is already connected to power socket), it charges very slowly - it was probably charging only in "USB mode".
SOLUTION: plug USB cable with AC adapter in to the tablet first and than into power socket - it switch to "AC charging mode" and charging more quickly.

[Q] Lumia 800 Battery life

Hi Guys,
My lumia 800 on 100% charging shows the remnaing battery 1240 mAh and full capacity at 1470 mAh.
If I keep the power source even after 100% of charge, the remaining batter capacity is getting increated from 1240 mAh.
I am confused whether I should keep on charging it even after 100% charge or not?
if you put your lumia in bed while being charged, you'll found something amazing
Please explain.
I think they're trying to say 'charge your phone while you sleep'.
If not, then they might need a therapist.
Getting the new firmware this weekend at nokia care. Will see the performance after that. Currently i am getting 12-15 hours with edge is always on.

Hi,
I always see people using the diagnostic tool "battery status". I've a "Detailed Battery Info" - section in the diagnostic tools too, and there are much more informations including a (as far as I know) never discussed "StateOfHealth".(see attached picture 1) I myself have no problems with my battery at all, and my value of StateofHealth is at 858. Interesting to know, what values people have, that claim problem with battery.

Lumia 800 Battery Life
With regard to the above comments, when i got the phone the battery life was so so. After downloading the latest firmware update it seemed to get a lot worse. One day it didn't make it all the way through & that was after just a handful of phone calls and a handful of texts. So I did the hard reset & suddenly the battery was great. I was using the battery saver admittedly (owing to the loss of confidence) but last night it reported I still had one and a half days charge left and had used about 30%. I would therefore very strongly recommend doing a hard reset once you have the latest update. I know it's a bind but if like me you have all your contacts and calendar synced to Outlook via the Outlook connector it's not so bad. The contacts & calendar just reappeared on the phone as if by magic once I put my Hotmail password in. I'll obviously be monitoring the battery for a while because it let me down at work before I reset it, but I'm pleased to say that I love it again now & would recommend it to anyone. It's a gorgeous phone.
Okey. Here are some numbers. We like numbers, as they don't lie or making things up.
Before factory reset my Current (Discharging) was around 180.
After factory reset it finds itself around 140.
I've tried with and without wifi, with and without data connection, both before and after the factory reset.
I guess it's like someone mentioned. Some application got stuck and caused the battery drain.
I'm going to reinstall my apps I had before and after each installation check the battery drain to see wich application is causing it.
A good OS shouldn't encounter problems like this. Nokia and Microsoft needs to work on the stability. The Lumia 800 AND the OS has a great potential but still lacks on several functions and stability.
I don´t have this problems.
I charged my phone yesterday evening (22 hours ago)
and still have 75% and 1d 5h left.
I phoned a little bit an was a few times online (Wlan)
Browser and Marketplace
The Phone is new and I hope the battery will get better.
I updated it, before testing batterylife on old version.
But it isn´t as good as my last phone:
my htc Trophy made about 5 Days if i used it like my lumia now
I don´t installed the app you all use to test your battery
(sometimes i think this is the app, that drains your battery,
because it is not wp7 that needs a lot of battery, my last wp7 phone had a small battery an very long live)
and...
.. i have no problem with loose buttons.
Factiry reset
Well I finaly took the plunge and did the reset. I now have a normal working battery (at least for now). Wish I had done this earlier.
I strongly recommend that anyone with battery problems does the same.

I have got a massive increase in battery life and am not quite sure how.
I uninstalled the diagnostics app and it seemed to go downhill from there (sure it's a coincidence though). At this point battery life was a joke, couldn't get through the day with light use. The other change at the same time that could have had an effect was switching to use the Nokia charger rather than the one from my Galaxy S.
I reinstalled the diagnostics app and also turned 3G off (work and home both have wifi). However, I have now turned it back on, and since then battery life is much better and the phone now easily gets through the day.
Maybe try toggling 3G off for a day and an overnight charge and turn it back on and see if it makes a difference.
There is something wrong at the driver level with this phone I'm sure.
My phone has been fine ever since the battery life jumped up, it's not a fluke.
I made 27 hours with heavy usage (wifi+3g+games+constant fb)
Mine has made 3 days and 14 hours (Not that heavy usage. Mostly texting and some calls) and it's got 18% left.
OK,
I read too much different views...
Tomorrow my new Lumia is coming
I am able to check it before do the payment.
So, what I have to do? To look in the menu for diagnostic tool or to dial ##634#?
Is it that the right combination?
Or just to pay it and to let it die without battery, then hoping to turn itself on with good battery life?
Please give me some advise..!

Have you noticed what app was causing it? Before my restore i had 14-17h left according to the phone. After the reset i had 36h left according to the phone...now 3 days later i´m back at 16h. It lasted for 2 days the good battery life...

Battery Life

I am seriously thinking about returning my Sony Tablet S.
I can't seem to get more than 3 hours out of this without a charge.
I play a full movie with wifi/GPS on and then i am down to 30%.
I do have it rooted and most of the bloat apps is gone. I check the battery indicator constantly and the biggest app using battery seems to be android so nothing is zapping my battery life.
Any ideas?
I think something is wrong with you're tablet, mine lasts for more then 8 hours without root.
So yes, return it and ask for a replacement.

Try and adjust the backlight intensity
When I first used my tablet the battery seemed to be gone in no time. I have found that reducing the backlight manually has helped. I would say there was a definite difference.
Thanks for all the responses.
Problem is this is for my kid. He don't really have the patience to wait for charges every day.
He like to watch movies on the tablet and play some games here and there. Considering he only use it for 3-4 hours a day, this is insane how short the battery is.
I thought i will never say this...but another android guy bite the dust and cross over to the evil apple kingdom (exchanging for the ipad2 with 10 hour battery life).

so we've all told you that it doesn't sound normal and that you should get much longer out of the device and your answer is "it must be android" rather than a faulty device.......
8 hours to 10 hours on mine, depending on what i do. with and without root, it doesn't change my battery life.
Mine about 8 hours
Had the same issue in the past... Delete all on USB and make a factory reset solved the problem. Now it run up to 8 hours.

Same issue and fix here.
I have decent battery life ( 6+ hours) but one thing that makes me wonder is the idle time.
5 hours of screen time is less power consuming than the tablet being 20 hours in idle. Has anyone the same experience?
Yes. In my case it's the 3G modem. Turn it off generally and only on when you use it.
If I compare this case with my iPad I have to say, that the 3G modem in the sony uses much more energy in idle than in my iPad.
My Tablet is WiFi-only. And WiFi shuts down when the screen goes off.
Battery use:
Tablet idle ------------ 49% --> 15h 8m 57s
Screen---------------- 37% --> 4h 56m 31s
Is this strange behaviour or am I just paranoid since this is a totally different battery usage than on a phone( e.g Sensation)?

I report the same type of stats...
Its using a lot of battery in sleep mode. But sometimes it doesn't, sometimes sleep mode last way longer but most of the time its about 25-30 hours in sleep mode and that is way too much...
I hope ICS will fix this, if not i may return mine.
And not 2g/3g/4g here, no celular radio here.. So, its not that.

Hmm. You do realise playing videos and having the wifi on in the background will cane the battery? Even more so if you're streaming said videos to your device via wifi. No doubt you've got the screen turned up full brightness as well?
Mine runs perfectly well and can last for a couple DAYS between charges, depending of course on how I use it.
Follow the tips provided by the others, you might get a fix. If not, get a new one from Sony. It's not a problem with Android - I suspect if you watch hours and hours of movies on an iPad you will still experience excessive battery drain because of the intensive nature of what you're doing!
Thanks for all the suggestions. If the tablet is for me to use daily, I probably would have condition the battery, try to delete all and then restart. However, it is for my kid and frankly it is unacceptable that a brand new tablet after watching one movie (just regular mp4 file i installed into the internal SD) is down to 30% charge.
I won't even start with the rest of the things i am disappointed with; the missing 6 gigs on the 16 gig, the screen little darker than i wanted (the screen protector I don't like at all), and frankly honeycomb in general is not that crispy and well developed.
I did end up getting a Ipad 2. After watching 1 movie, the thing still got 80% juice left....is night and day. Screen is sharper and brighter and most importantly it last more than a day without charge.
I don't want to hype about ipad here and i am still an android fan (i got 2 android phones), but the ipad really is WOW compared to the current corp of android tablets. Yes i am disappointed i won't be able to "tweak" the ipad like i can with droid pads, but Apple OS is so much better developed than honeycomb or ICS for that matter that really you can live without the tweaking.
For all you guys, with Wi-fi only (and 3G if you like the solution), before putting it to sleep put the device in flight mode. I've done it on mine and it was asleep for 4 days while I went out on a journey and when I came back only 30% of battery was gone...
I honestly can only fault the ipad in the sense that a media device, that for all intensive purposes is basically a more convenient option than a laptop, does not have flash support. Quick web browsing on tablets is great but it's useless without flash :S. Damn apple. Other than that I think the iPad is pretty great, especially now that the pricing for the new iPad has become alot sharper than in the price. Obviously to combat the success of Android tablets of late. But all I want out of a tablet is a bit of web browsing here and there, a couple games now and then and a nice digital photo frame to boot
I don't know about everyone else, but I have no desire to flash the crap out of my Sony tablet like I do with my SGS2. Now that I have root access it's doing everything I wanted it to do (and should have done!) from the start. So long is it's stable and responsive I'll be happy with it for a few years at least.
I was never happy with my tablet from day one but for me it was just software - sluggish and app incompatibility - a factory reset and root has fixed all that now. Never once have I had an issue with battery life. Sure as hell out-does any gameboy/ds/psp I've owned. Standby will last weeks if I don't touch it too.
So to those of you getting around 1-2 days standby time, something is seriously wrong with your tablet. There must either be a fault with your battery itself, or some app has gone rogue and just keeps it awake the whole time. i dont think any type of conditioning your battery will heed any results;
I didn't condition my battery at all when I got it and it's just fine. I played it with the 5% charge it had out of box till it died, got home, charged a bit, played with it till it shut off again, then when it got about 1/2 full just took it off charge and played with it again. Now it normally gets charged every friday whether it needs it or not.

New XTZ == Fast battery drain (5% in 5 min)?

Hi all,
I just purchased a Xperia Tablet Z 32 Gig Wifi (SGP312) and am seeing an amazing amount of battery drain. I was using the kindle app and dropped about 5% battery power (96% to 91%) in about 5 minutes. Being that I just purchased this tablet from Amazon I would like to know if this is normal or if this sounds like it could be a hardware issue? Also, does someone know if the custom roms (e.g. CM10 or CM11) have better battery life?
Thanks!
Dave
Ps. I am running build number 10.4.1.B.0.109

i have a similar problem with the 16gb...which i didnt buy brand new. But i did get the updae from 4.2 to 4.3 when i bought it, and i believe its a
dirty update issue. Im going to wipe/restore it to make sure im running clean...usually fixes things on the Galaxy s3/s4 devices..........
the battery in this tablet is quite a bit smaller than other tablets, the galaxy 10.1 2014 has a 8200mah battery and ours has a 6000mah battery, i bought this tablet having an idea that the battery would be poor and thats what i got.
I generally leave mine plugged in most nights while im on it or it will just run out and not last a whole night.
I have always just seen this as normal for this tablet though.
reflash the firmware. Normally 2% battery loss overnight can be considered great, not 5% in 5 minutes.
Sorry if this doesn't help you but this is what I do and I have at least 7h usage on mine now from a single charge.
First up, if you are rooted try Greenify from app store, it saved a lot for me just doing all none system apps that don't require notifications or autoupdating (widgets).
Next up, drop your screen brightness, I regularly run mine on lowest setting. This isn't an issue as much if you don't mind removing Sony shatter protection on screen as it slightly darkens the screen, please be aware this is designed to stop your screen shattering if you drop it so do it at your own risk. I also use a generic matte screen protector to stop finger prints so you may not have this issue.
If you use custom ROM, most have performance settings, so if you don't use tablet for heavy gaming, you can save a lot of battery here by using power save settings and conservative processor governor. Again be careful with this if you are unsure, don't do it.
Lastly, most modern tablets etc have a fairly significant improvement the more you use it. Always try to run your battery to 10% or under before fully charging, however don't run it flat because you will most likely have issues.
Clean master is another app that helps me too. I turn off all settings except auto clean when screen turned off. Then go to memory boost and hold any apps you need running without being closed and press ignore.
Hope this helps.

Changed a battery. No much difference.

My N6 is almost four years old. Running LineageOS 15.1 for now.
1. Screen-on time is awful. OK, if I have 120 minutes till it dead meat.
2. Less than 50% battery results in very likely self-switch off. Sometimes it can be rebooted, sometimes not. Power connection resolves the problem.
So I decided to change the battery. It took 2 hours. 20 minutes of the actual work and for about 100 minutes I looked for a proper T4-screwdriver I put somewhere.
New battery = same situation. Nothing changed. The battery I ordered from the USA and it wasn't cheapest on eBay. I ordered two batteries actually.
Resuming I see the problem, not in battery or not totally in the battery. Looks like the problem in the aging power distribution subsystem. Capacitors etc.
This phone may be cleverly designed to hold a very specific timespan. It's time to retire.

I recently bought a N6 in great condition because I was refunded my money for my Nexus 6P. The phone did need a battery replacement though. It throttled under 40% and had early shutdowns.
I changed the battery (Cameron Sino) and modded my frame and back while I was at it.
The phone does run smoother (although no matter what rom I try, it always slows down to an unusable pace after a week or two) and stopped throttling.
I however do not get anywhere close to the SOT some of you guys are getting.
The most I could get is probably 2h30m if I'm lucky. Mostly I get around 1h30m to 2h.
I really want to get this fixed because I plan to use my N6 until the new Pixels arrive (which is still a long time).
I do have my Moto 360 connected but this is not the problem. I ran a clean rom install without my watch connected and bluetooth disabled and did not get more battery life out of it.
Edit: I'm running Nitrogen OS at the moment.

I'm deep in concern Moto implemented the N6 radio module or the radio flash or vendor or any other proprietary in the way to interfere with a proper day to day work.
Artificial aging promotes us to buy new devices every 2-3 years. But from the performance point, our 32bit N6 is still adequate.
Would be happy to get it to my kid instead of buying another device for him. He already killed my old Note 2 and close to do the same with J7.

I had a similar problem on the Nexus 5 a while back. What I did was to put the phone in recovery and let it drain till the battery wore out then charge it back to full while still in recovery. It took a while but seemed to stop the battery from both shutting down early or reaching 0% prematurely. Sounds weird I'm sure but it had an affect. Nothing to lose to try it.

I had a similar experience, changed out the battery in my device back in March. Performance is marginally better, but it still turns off at or around 15%. Nothing new out there to entice me yet, though Best Buy does have a great deal on the Pixel 2 XL with Verizon right now.
I was thinking about what it is about the Nexus 6 that has kept me with it for longer than any other phone. I decided that one of the many things I like is the 16:9 aspect ratio. The phone is thick, for sure, but 16:9 is just right. Not sure if I am ready for the 19:9 or 18.5:9 or whatever else is going on out there.
I just keep my phone plugged in at work, helps me get through the day both battery and performance wise.

i was having that problem on nougat around 40% ( pure nexus), used it for over 6 months, moved to oreo for couple of weeks. both aosip and lineage os. its worse. i am afraid to let it go bellow 70 because its my daily driver and i don't have a back up phone right now. i am not even rooted now because it adds to instability.
Update:
Within a week of my last Post it was so bad that I had to have the phone plugged in all the time. If unplugged phone would turn off around 95%. If I pull down quick setting bar it would shut off immediately. So I get a battery and replaced the old one. Took me an hour and half to fully charge more than 2 days ago. I'm not really using it. Off and on I would turn it on to check emails, browse little bit, play some videos etc. I'm at 11 percent now. Battery saver turned on at 15%. More than 4.5 jour sot.
At 9 percent now, no shut down yet. Not even one. I'll plug it in now.
Another thing I recently discovered is that revootimg into safe mode and then rebooting back in to regular mode clears up some issues. Anyone having random shutdown issues might want to try this. It seems to have good results so far for me. Phone is now more fluid than it has been since I bought it.
It's time, darling...
Donated my N6 to my kid. Bought OnePlus 6 for myself and 5 for my fem. My old N6 reflashed stock and it looses battery pretty quickly. Will try to do all those recommendations from above...
have any of you tried rebooting to bootloader, selecting Bootloader Logs and holding the power button down till it reboots trick?
For my N6 i put 2 battery in parrallel, and i got more than 8hours screen on !
But no more back-plastic-plate..
At least, i can handle a big day
For charging i'm force to use only fast-charge charger, under 800ma it take 20hours for full charge ! (5h in 5v1500ma and 1hours at 9v2A )
Lineage 16 - Popcorn Kernel + undervolt cpu -30mv*
Problem solved, at least 1more year with this phone for only 15$

Just buy 2 new battery, verify the voltage (they have to be the same before soldering) on one diconnect the BMS and use your soldering tool to put the two battery in parrallel
Keep using one BMS for connecting to the phone
You'll have to cut the plastic to fit the two battery, and you'll never be able to put the battery cache again of course, use some tape of your favorite color to protect the back ( if you don't put tape you will cut the BMS cable or damage the button connector )
That's all ?
Just want to share my experience...My nexus6 used as backup phone got same problem. I only use to stream live video and need to connect it to charger or powerbank to avoid random reboot. Then, last month I accidentally found e-commerce shop sell N6 battery around [email protected] and I tried my luck to change the battery... after changing to new battery and used almost 3weeks I found no more random reboot but battery life is not great in idle (using android9 custom rom) then I switch to android 8 custom rom..idle is improved but sot only can get 3hours only. Check with accubatery shows 3100mah...

ROMs (HTC us/T-mobile) U11 Life

I think we should start working on some roms for our device. It seems no developer will come to our aid. I miss Roms like RR AOSPE etc. It can really be nice if we saw them here. Instead of continued waiting, its time we used google and come up with some roms for ourselves. Build fron sources? Or porting? Whatever works. We can port Roms from devices with similar processor or from the android one HTC U11 life. I have a feeling it will be easier to port the HTC u11 life android one rom as hardware is the same, so porting kernels only should be able to get it booting. I would have gotten porting but then am off pc at the moment.
This takes lot time to do the more people we have it will make things lot easy to bring out
Hi guys! I agree with you. I believe we must make "roms".
I have 2 "Life", the first is T-Mobile while the second is Android One.
Above the T-Mobile, I mount a US 8.0 stock rom with unlocked bootloader and root. I removed a lot of stock apps and mounted the stock gapps!
Instead, Android One received the "Pie" update. This device, for now, let him stock!
It would be nice to have "pie" in T-Mobile too, but the system partition is completely different, and without "s-off" we are dead!
Excuse my bad English.

Only 5/7 hours? It's too little!
I get two days of use with both Oreo and Pie.
WiFi and mobile data always on. Position off.
If I use the position with Google Maps navigator things change, lasting one day.
I'm afraid your battery went friend! but cheer up, in this phone you can change the battery without breaking the display like in the HTC 10.
Obviously, you need to check the chargers!
I have noticed that: depending on what charger and use it changes the life of your battery. I have two chargers, the first is an old 700 milliamper charger, the second is a new generation 2.4 amp charger and QC 3.0 port.
When I charge the phone leaving it all night with the 700 milliamper charger the phone lasts me two days. When reloading the phone using the 2.4 amp charger the phone lasts for a day.
Slow charging is always the best!

I did also 2 days charge up to 80% and then a full charge
Still nothing
