Battery advice for constant hotspot - Galaxy Note II Q&A, Help & Troubleshooting

I have the n7105 and am fortunate enough to have an extremely generous 80GB cap on my LTE service. Its also insanely fast, so I am now using my phone as my primary internet hotspot at home and in the office. I'm afraid this might be harming my battery because of all the charging and discharging. I charge my phone overnight. By early afternoon its down to 40% and I normally charge it back again to 100% then by bedtime time its again 40% and I charge it overnight. Would it be better to just leave it on the charger in the office and most of the time when at home? Or is my current schedule okay?

Please don't all answer at the same time, makes it hard to hear :silly:

I used my Note II (and DHD before that) as hotspot for 3-4 months (my router died) and I just kept it on charge while being used as HS. Didn't notice any side effects on the battery. Hard to tell what is better, to leave it in charger or constantly discharge and then recharge.... but since the battery is replaceable, I wouldn't worry too much about it.

Battery Life on IIs

Hey what have you guys n' gals been getting off your XDA IIs for battery life. I am away from home just for one night this week, and have forgotten my charger (Must get a sync n charge...but where!!!!) I'm only using PDA functions and Duality Email....and battery is already at 83%
Will it last 48hrs!!!!! We'll wait and see!

Obviously using it as a PDA does use more battery life.
With my phone 'off' (well pda bit off) and WiFi off, over a 12 hour period of inactivity I'll use maybe 5% of battery, so when it comes to bed time your battery use will reduce.
if you're away from chargers I'd advise keeping wifi off, it's the battery eater portion of the functionality. a little light GPRSing shouldnt hurt if you need email, bluetooth isnt a big issue, but if you need to last 48hrs, dont touch the WiFi :twisted:
Also I have noticed that my battery goes from 100-95% REALLY quick (like 10 mins with only BT on), but then takes maybe 30 minutes of wifi browsing to use a similar 5% in the 50% range!?!? non-linear battery consumption maybe? Might be just mine.

I've noticed the same but, conversely, when charging, it takes longer to charge the last five percent than the rest. So, I put it down to the Battery monitor API. These things are never 100% accurate.
As for battery life, two days from normal useage and three and a bit days if I'm careful. I have no problems going for a long weekend and not taking the charger as long as I have no plans to use it intensively.
I find reading an ebook with mobipocket also kills the battery at about 10% for every hour and nearly treble that if I'm listening to music at the same time.
1 Day, its usually down to < 30% come time to goto bed. But then, it gets well used.
So, the question has to be asked..... Who has the charger by the bed?
/me raises hand.
Sync cradle is at work... which charges too.

Battery Life on XDA
If you turn ON flight mode you will find battery life will improve but you will not receive "always on emails".I've got a feeling the phone wont work either (i don't use mine as a phone so not sure).I know when you turn flight mode off again you will have to enter PIN no.
I used this method when I was in hospital for a night and they would not let me charge my XDA.
yeah : flight mode = turning off the phone part
I have a brodit cradle in the car , charges it extra while commuting
As default when you get the phone, it will ask for a pin number. This can be disabled though through the software!
Flight mode will of course save battery - like said - its not using the phone functions which are probably the most battery draining.
I have to use my charger twice a day but i do cain it as my job is so ****ing boring! i hope to god someone invents a....
Solar panel charger
so i can go campin in wales on ma scooter and not need to sneak my phone into the pubs wall plugs all the time
I have a brand new M2000.
I took it off charge at 08:00 this morning.
I got to work at 09:30 and started using it.
I had bluetooth on with headset and I was using wifi on and off.
I started getting low battery warnings at 15:00.
That is very poor
I have BT on and can run from Thursday night through till Sunday without a problem. Though I do get worried about making calls on the Sunday. If anyone has a description of how to convert an XDA car cable to XDAIIs I would be gratefull.

Problem With Battery

Hey guys, I just got the droid incredible 2 and I first had the LG revolution but the 4g and the screen size made the battery drop down quick. I played with it for 20 minutes after it being fully charged, changing settings, and the battery went way down to about 80%. So I exchanged it for the HTC Incredible 2. They told me the batter was way better.
I went to the Verizon store to tell them the batter dowesn't last as long as expected. My Iphone 4 would be on all day, texting, pandora, email and web browsing and I still came home from work with battery left. My droid gets used from 7am to 1pm and its pretty much dead by then. They made me change the background data off, sync only email and weather, and download juice defender.
The batter still dies by 12:30pm after charging all night.
I have read all over people are getting excellent battery usage but I don't really know what to do to get the same. It is not temp rooted. Any ideas? Also, at work, in the building the data coverage is not so good so I usually do nothing but text on it and it still dies by 1pm.
I can't really say how well mine would do on the standard battery because I bought the extended battery immediately after getting the phone. I've been unplugged almost 15 hours and have 38% battery and I have sent/recieved 40-50 txts, 20 mins phone, browsed internet for 30-45 mins, played games around 30 mins, and listened to pandora for around 45 mins.
I would recommend the extended battery, it's $50 at verizon and I haven't even come close to killing it in a day.
Does the extended battery make the phone bigger? I'm thinking it would be thicker on the back. Would it have any drawbacks as to cases and stuff like that?
I'm not sure why mine is so bad, prolly because I am in a secure building and signal doesn't get through constantly. I'm surprised, I thought my iphone had bad battery.
the extended battery does have a thicker back. and yes, there are currently no cases for it, so there would be an issue there if having a case is very important.
as to your current battery, if your in a biulding with bad signal, that will most defintiely affect your battery life as your phone will have to use more battery to try to find a good signal. additionally though, the phone battery does seem to improve after about a week of charge/discharge cycles. not sure why this is, but i have seen it on my phone and seen many other report the same.
The battery sticks out a little more than 1/8th of an inch I would say. However, IMHO it protects the camera lens and flash lens from getting broken and I never really like using a case anyways.
I have amazing battery i charge it to 100 percent unplugged after then go to school texting 100-200 average everyday internet music by the time i get 3:00 i still have 80-70% and i'm 13 so imagine how much i use it and it still stays at that percentage
Having a phone in a building (or anywhere) the signal is weak is a drain on your battery. If your iPhone was with AT&T the signal may have been stronger where you work than with Verizon and may have therefore contributed to better battery life.
Also, if you didn't FULLY charge your DInc2 and FULLY discharge it right when you got it, you should really do a factory reset and immediately do the following:
Charge the phone for at least 8hrs with the power off, unplug for a few minutes, plug it back in. The light should only remain red for 10-20 seconds before turning green, otherwise this unplug-plug part should be repeated a few more times always letting it remain on "green" for an hour before unplugging an plugging back in.
THEN power up and use the phone until it shuts itself off because the battery is drained. Let it sit for a few minutes, and turn it on again. It should sut itself off again pretty quick. Let it sit, turn on again. Do this until it wont power up at all after sitting untouched for a few minutes and your battery is then fully discharged.
Now you can plug it in and start the charge part of the cycle as lined out earlier. Once the light turns green 10-20 sec after plugging it in again you have completed one "cycle".
This may sound excessive, but I'm kind of a nut about this kind of thing.
I didn't do anything special when I got my I2, am a realtively heavy user, and have an all day battery life. I'm pretty careless with my features being left on.
If you can't get it to last all day, either you are a much heavier user than I am or you do, in fact, either have a battery problem, or a battery calibration problem. You shouldn't need to calibrate the battery algorithms, but I guess it doesn't hurt to try.
I wouldn't say I am a heavy user. I normally text while I am at work and check facebook a few times. I also listen to pandora most times. I work for Vanguard and most people here have Verizon I believe. I was told when I switched from AT&T that signal should not be a problem where I am at. My Iphone 4 would get used much more and it too would have signal problems as well until I turned 3g off but it would last way longer than the droid.
I guess I can try the factory reset and full charge cycle this weekend but I'm not sure what Verizon can do for me either so it may just stay like this
this is bump charging no? (well the part about how to charge it). i spoke to am htc rep that said that bump charging will significantly decrease the lifespan of your battery life and therefore is highly not recommended.

I just got mine on Sunday, but even yesterday I was texting and surfing a fair amount yesterday and went to bed with the phone at 61%...
I am sort of amazed, I think Verizon has taken the underclocking thing and put it to work on the official release... at one point I turned off the screen for what amounted to an hour and when i turned it back on it was still the same battery level.

if your comparing battery life on the dinc2 with 3G on versus the iphone with 3G off there will also be a pretty big difference. if your tuirn off 3G on your dinc2, i would imagine battery life will be similar or better than your iphone had with 3G off also.

No I was comparing the Inc 2 to the Iphone with 3G on. My iphone would also last longer if I turned 3g off and just used Edge or whatever it is called. I don't think I can do this with the droid until it is rooted or download an app to do this.
I turned off juice defender and we will see how it goes today. I don't really like apps running in the background and it was turning off data eacht ime the screen locked.
I think the biggest difference is the verizon signal. The battery on this phone is amazing for an android device. While it is still nowhere near iphone 4 status as far as battery, it shouldn't drain like that. Have them either swap you a battery or the phone itself.
I'm a relatively heavy user. Especially with voice calls and I can go a day and a half easy.
But I also run launched pro with only a couple of widgets. To me sense is a battery hog.

What would I do to go about swapping out the battery or the phone itself? Should I go back to the same verizon store? Or call them on the support line and try to get a battery or new phone that way? I have no clue why it is draining like that either, the signal can't be that bad, I literally had the same signal with AT&T in these buildings.
Well, lets be honest, one of the things Apple really puts a lot of time and effort into in their development is long battery life. It wouldn't surprise me to see the iphone outlasting most Android devices.
In any case...
While I don't need to, I do charge my phone while at the office. If you have a desk job then I don't see how this would be problematic. My work day usage includes 2 hours of bluetooth streaming (in my car to the stereo), media playback (music/podcast), and mapping with gps and 3g data (this drains my battery pretty quickly, but that's relative...it's about 15% per hour). Outside of that, my battery drain is quite low.
I only started charging at the office because I like to keep my battery as full as possible in case of extended emergency that requires being away from a charging source. It's that whole boy scout be prepared mentality I have. Besides, if you have the opportunity to charge, why not? It seems to charge pretty quick anyway.
I can charge at the office, but normally I forget the cord at home. Not a problem to buy another one but still. I was just concerned because I hear people getting 15 some hours on one charge and as of right now, my battery is below 50% since I just got back from lunch.

take it back to the store, and if that doesn't work then call. but the store would probably be a better bet as they can give you a new phone or new battery there whereas the phone support, you'd have to wait for the shipment.
Seems as if they were not able to help in store the first time. Rather than have someone check it out, they had someone come over and tell me I should turn off all the sync and data features. So I did do that, but then why did I get a smartphone?
It's possible you have an app that is not allowing the device to sleep. If it can't sleep, it will drain the battery much faster. You might get 8 to 12 hours awake yet idle.
Are you using many third party apps? If so, have you considered going through them, removing them one at a time, until you find the battery doesn't drain so fast anymore?
If you go to About phone in settings, then Battery, the last item will show awake time. This should be much lower than your Up time.

[Q] When do YOU charge your phone?

So recently I have been wondering if the way I charge my phone could negatively affect it. So I'm wondering when, and how you guys charge your phones?
I personally drain it as much as I can (to dead if possible), then plug it into my wall charge and leave it plugged in overnight. (Since I kill it right before I go to bed)
Nah, just charge whenever you need to. I would avoid completely draining it as that can damage lithium batteries.
At night. Wall charger.
No reason to be worried about negatively affecting your phone by charing it a certain way. It's going to be okay .

He is safe, this isn't a concern as there is internal regulation in the battery pack itself. It cuts out output to prevent completely draining.

Might I add I have the extended 2100mA battery.
I charge when needed (keep a charger nearby at all times) and am only concerned with keeping the battery from dying and leaving it at full charge for more than a couple of hours. Most of the time this results in once a day charging before bedtime but if I'm downloading or tethering all day (recently lost my wifi connection) then I'm looking at 2-4 charges a day. Kinda lame but eh, electricity is cheap.
I charge it when it needs to be charged.

Your practice is bad. The deeper you discharge a battery, the shorter its overall battery life will be. However, it's also not good to keep topping it up, thereby keeping the batter in a perpetual high voltage state. Just use it normally, and charge it at the end of the day.

I hear waiting till level gets to 40% to charge is suggested. Keeps the battery stuff moving properly. Think I read it on CNet

Meh I just charge it whenever and haven't noticed a bad effect on it yet. I put it in and out of car dock multiple times a day. Always charge it at night when sleeping. And if I'm at home all day using nit a lot I might charge it an extra time if I wasn't getting topped off in car dock.
I charge my phone at night while I sleep. Oft times it's dead from being charged he preceding night.
Another question. How is cell service in the majority of users areas?
I have no service at all for at least half the day (school and home). At work I have good service, and I'm only ever in other good service areas for no more than two hours. I finish off the day with an average screen on time of one hour and thirty minutes.

My phone gets about -90dBm on LTE near Chicagoland area at home. At school, my signal drops quite a bit, and I get about 2 bars (No idea what dBm, never checked.) but overall, I usually have great signal and speeds.
I also average about 11 hours of just normal use (for me, checking it quite a bit, playing games and listening to music)
I rarely plug my phone into the wall outlet. I have the pogo pin dock so during the work week I have it sit on the dock all day and it is fully charged when I come home from work. So even with heavy usage at night, I never have to plug it into the wall whether that be after work or when I go to bed. The next day I just charge it back up at work.
The only time I run into battery issues is during the weekend. But since I have two batteries they normally can get me through the whole weekend without having to plug it in to the wall too much (again it depends on usage).
Really depends on the situation. If I need the phone next day and won't have access to charger for sure I'll charge overnight from USB port on one of my comps that is on 24/7. Usually I don't let the battery go below 20% before charging. I'm also always charging the phone when driving since use my GNex for listening to music with Spotify and always force the screen to stay on during those times. Don't want the battery to drain when driving due to having the screen on for long time.

How long does it take to charge your battery?

I had a One X that took forever to charge, based on its battery consumption. I went back to an Iphone which charged quicker and didnt use as much battery when playing music. Can someone tell me if the Optimus G charges quick? How fast does it take (wall, and computer) - I charge my components while riding a bike, so the less pedaling, the better
I don't have an exact amount of time nailed down (never timed it or anything) but I find with the wall charger it does recharge it pretty fast.
On usb however its pretty slow.. probably more than 4 hours from drained I'd imagine with USB.

I use a 1200 mA current charger and it will take about 2 hours (or few minutes more) to charge from 5% to 100%.
It's fast enough for me.
About battery drain, I have to say it'a all about your usage habbit.
After a hard reset I powered on E975 and let it standby for 45 hours.
The battery drained from 80% to 69%.
NO SIM card inserted.
GPS and Android Beam(NFC) enabled (but not active).
BUT, when you use it with screen on, the battery drains quickly.
Hope it's helpful.

Overheating while charging on Wireless charger

Hi, I have Samsung Galaxy S20+ G985F/DS (Exynos). Few weeks ago I get a new company car, which has wireless Smartlink+ for android auto and apple car play. I was used to use cable, but few days ago I decided to bought wireless charger (Baseus Cobble 15W) to my car. Since then I have problem with overheating my phone when I am using wireless android auto and wirelessly charging it. I am using Spotify and Waze together and at same time I am charging it with wireless charger, but after few minutes (usually 5-10 minutes) it disconnets with error that my phone is too hot and it will continue charging after it will be colder. When I try to take a phone its damn hot. Is this normal behaviour or my phone is broken?
Running the battery hot will cause premature aging fast; stop doing it.
Software may be using a lot of cpu cycles; wayward apk(s).
Correct this if so.
It's not a good idea to charge and use the phone.
Get a fast charger for the car; you get about 2% per minute with a 25 watt one in fast charging mode between 40-65%.
A 25% charge should last 2 hours.
Li's love frequent partial midrange charge cycles and will get hundreds to thousands more full charge cycles when used like this. Partial fast charging does no harm as long as you keep the temp in the 80-99F range.
Try to avoid charging when under 80F and especially if near or below freezing temperatures.
Been using my 10+ like that for over a year, the battery is in very good condition to spite near all day use.

Well thank you for your answer, but I don't understand you well. Your post is very confusing. But from what I understand, you simply tell me, that I must buy normal wire charger and I must stop using wireless charger because using it is not good? But that is not answer that i want. Because I don't want to plug cable to phone, because when I have wireless android auto in my car, its useless. For example my colleague have car with built in wireless charger. And from what you told me, he can't use this built in charger because its bad?
You have two issues.
App(s) that are using excessive battery.
Charging while using.
Both are best avoided and both drive up the temperature.
Of course you can do what you want but battery longevity may take a hit in doing so.
Karma Firewall is useful for finding unnecessary bandwidth hogs and some of the battery hogs. Start with that.
All wireless chargers make phone hot. Even if you use it at home and no aps are open.

Excellent point.
A damp rag can be used to reduce the temp.
Unless the charge port is broken wireless charging just doesn't seem like a good modility.
Even at high frequency and optimum primary/secondary winding gapping air core transformers are notoriously inefficient.
These batteries are power hungry critters...
Man, I know what you all are saying but imagine covering your phone with a damp rag when changing, imma die of laughter if I see that anywhere. I know it's gonna work but it's going to be funny af
Mine did the same thing, it was 5 days old when I saw it the first time. If you insist using your phone and charging it wirelessly disable the fast wireless charging option from the settings and you are going to be good to go, but don't expect the phone to charge that much, maybe 2% in 5min, something like that probably. It will not overheat, tested it myself. Be careful, if it continues to overheat even with fast wireless charging option disabled stop using the charger when using your phone. I have a suspicion I burned my coil like that, it only took 5 or so times where my phone said that it can't continue charging because too hot. I hope that wasn't the case.
