Possible Battery Charge Limiter?

Guys,
I have a sony vaio and i have a mode called Enable Battery Care Function where the app restricts the battery to stop charging at 80% which would multiply the life of a notebook battery (says Sony) there is another mode super care function @ 50%. I find this handy because i always have the power plugged in for my laptop.
Similarly i always have my HD2 plugged in to my notebook, so i keep recharging and may be over charging the device too and burn my recharge cycles. So can an app limit my charging to 80% or so? anybody share the same feeling?
Maybe an app can help.
Thanks,
Raj

commonsense would say it stupid.
stinginess would say it smart.
unless of course, you plan to use that phone for few decades where no more battery would be on sale. then you better start take good care of that battery.

Well,
I never use a phone for more than an year, you can see my list.. but what i do is to maintain it properly. I also have 2 spare batteries with me. so answer to my question if you know or pass.. this forum is no place for crap for someone with post count of 15.

A Lithium Ion battery should never be charged to 100% or fully Discharged. The famous 80-20 rule is applicable here as well, though in a different way. Charging to 80% increases battery life.
Don’t wait for full discharge, charge it frequently. Keeping the battery near to 80% always, gives better life. This is also what many vendors claim as “memory effect”.
Every battery has limited Full charge-discharge cycles. Of the order of 300+. In other words a typical phone battery can be fully charged/discharged 300 times. Doing more frequent charges, as specified in point #2, will increase overall life.
During first time use (when the battery is new) don`t use it till its fully charged. This is why it is always written on manuals “let the device charge for 2-3 hours”.
Best way to increase battery life is Not to use it. If you keep AC power plugged in on your phones, keeping the battery at 80% (as in #1), your battery will last longer. Though discharging it once in a month would be must in such cases.
Surrounding temperature contributes a lot. Colder weather gives better battery life. So make sure your cellphone doesn’t overheat, if it does, find ways to keep it cool.
When not in use for long, store the battery keeping point 1 and point 6 in mind.
Apart from this there are specific tips to elongate battery life which are related to user’s usage:
Keep the screen brightness to as low as possible. This can reduce battery consumption by upto 40%.
Don’t do heavy tasks like gaming when running on battery. This often uses High CPU graphics which drains battery faster.
Kill background processes that you are not using, multitasking is one serious battery killer.
Use headsets for long conversations. This will give you 40-70% improvement in talk time. Why? because when you hold the cellphone in hands, your body absorbs most of the RF.
Use software like WMLongLife, it can increase battery significantly. It does that by switching the network mode to 2G automatically when you doen’t require 3G

Well, I have my Sony Vaio TT92 with ext.batt (big one) now for 1,5 yrs in everyday use and until February had it in batt-save-mode 80%. It lasted about 10 hrs. with 50% screen-brightness and volume 50 %. Now in Feb it started to last only 7 hrs and less. Now I switched to full charge to get 9 hrs. of working time.
On the other hand I have my HTC Touch HD now for 2,5 yrs and until Dec. 2009 in full use, since my HD2 arrived as backup phone with a "xtra" sim-card so both the HD2 and Touch HD are ringing. I reduced e-mail download on my Touch HD to once a day and the batt after unplugging at 6 am shows still 98-99 % in the evening at 10 pm with the original batt that came with the phone.
What do I want to tell You: drain and charging cycles do not seem to affect small batts with little Ah-drain as much as notebook batts, so it seems to me.
For my HD2 I bought the ext.batt and it is fine for 2 days of full work with it. When I see it deteriorating I will buy a new one.
Or, more probable, the HD3

[Q] How to take good care of battery ?

Ok guys, so recently I'm starting to use my smarthphone ( xperia ray ) to do lots of things and one of it is as my Agenda. Now the real problem is, every time my phone is running out of battery I must charged it ( obviously -.- )
And everytime I charged it I always shut it down because people say that it's better to shut i down so the battery will have a long life
Can you guys tell me how to take good care of a battery ? And is it true what I said ?
( Sorry for my english -.- ):fingers-crossed:

I don't really think that offline charging will have any impact on battery life.
Anyway, from my experience the best way to conserve your battery health is to charge it in full cycles. That means not to charge it when it's on 40% but let it drain to almost empty or empty and then let it charge until it's full.
Your battery life will become worse with time. That's how rechargeable batteries work. Every battery type (Ni-MH, Ni-Cd, Li-ion etc.) has a different amout of recharge it can take. It won't recharge fine 100000 times and then after the 100001st time "die". It's life gradually shortens.
That being said, if you haven't used a phone/battery for a long period of time, it is always wise to drain it totally and charge it full for 4-5 times and then you will notice an improvement in battery life.
Also lower your display brightness. Display is eating most battery power, especially if you're using your phone a lot

Never over charge,like after charing 100%also never plug in to current,as it bring downs the battery performance later.....
I have wasted my 2 mobiles battery in same way.
I even fear for battery bust!

Battery life is affected by temperature, so try not to let your phone stay at high temperatures for too long

You can't overcharge your battery, that's a myth. It charges to 100% and then it stops charging, even if it's still connected to a power source. It starts charging again when it drops to 95% (hence why you sometimes see "97% Not charging" on your phone).
And yes, in some cases temperature can affect battery life but usually only in short-term. Still, it's a good idea not to leave the phone in direct sun in the summer or in your car in the summer. Extremely cold temperatures can affect its life too. Most batteries actually have written on them what temperatures they can withstand.

Battery lifespan tips?

I have a Lenovo laptop and its got a great software that helps to maintain the battery lifespan. Is it the same for phones where you should once in a while drain the battery to empty, also should you only do a full charge rather than topping up?
Im into emulation but that tends to be a battery killer so advice would be really helpful.

Nope just keep charging it. Don't drain it completely

You sure, in the two weeks Ive had Ive already started to notice a difference.

http://arstechnica.com/gadgets/2011/02/ask-ars-what-is-the-best-way-to-use-an-li-ion-battery/

Interesting. What about when doing battery intensive stuff like playing games or using emulators, would you suggest playing with the charger plugged-in or to instead recharge when the battery goes low (obviously not too low).

I don't think ot really matters, just don't be afraid to put the thing on charge whenever you want realistically

Thanks again. Last question, after a whole day usually my battery is quite low (below 30, usually below 20). Is it better in those cases to do a half charge and then do another half charge later, or is that the same as doing a full charge in one go?

Is it okay to charge overnight ?

Hello guys sorry if it is an innapropriate question but I want to know if it is okay to charge my s8+ over night.. does it damages the phone battery or not ? Thanks

I wouldnt. Doubt it would but would but i find it pointless. It charges pretty quick and wouldnt want to leave it charging for 5+hrs The battery is superb i would quick charge a few mins before bed. Ive gone to bed with 19% and had 17% when i woke the next morning.

Yeah I know but i work in the morning at 7 thats why . I use it at night leave it at about 10%

Been doing that with my phones for years, haven't had a problem yet.
technically with Lith Ion the less you let it die all the way the better it is for the battery.

It's not going to outright destroy the battery, but definitely better not to keep it on the charger. I cannot speak to your schedule and work environment. I charge mine mid day at work. If your usage is generally the same on a daily basis, just find a spot where you can squeeze in a charge or two during the day.

Always changed overnight for ever I can Remeber. Never faced any issues.

i leave the phone on the wireless charger. it better for the battery or is the same?

let me clear it..
1st of all in modern battry charging technology overnight charging doesnt harm battery at all as lith ion batt never get overcharged..bcoz once its 100%(max threshold) charging stop and phone use batt powr
after that once it get around 100% ( lower threshold) it start charging again...
STILL I PERSONAL ADVICE TO CHARGE OVERNIGHT WITH FASTCHARGING MODE OFF(((OFFF)).

As far as I know, technically wireless chargers are worse for the battery than a wired. They produce more heat, which technically will have a larger impact on the battery. That being said, I doubt there is any appreciable difference.

Good point. Does ths fan cooler on the wireless one prevent as much heat?

The battery retains 95% battery life after a year of normal charging, I wouldn't worry about depreciation. Relax and enjoy the phone

No, you can charge your android overnight as they are smart enough

Boooom! Lol.....just kidding I hope

Stick with the samsung fast charger. I have a lot of other ones, and only the samsung stay cool (fan) and doesn't cycle like the cheap ones do.

Yes, as most have said, you can charge overnight. I have done this every single night for years, on all my flagship devices. Smartphone batteries have technology in them to stop charging when they hit 200% and only trickle charge them. It won't do any damage or won't cause long term battery life issues.
Just turn off fast charge if you're going to charge overnight.

I've also heard the opposite, as wireless chargers charge slower they put less pressure on the battery which helps it not degrade as fast. How much difference it would make either way I dont know, possibly hardly any.
I do know keeping it between 40-80 is widely regarded as being a lot better for li-ion battery degradation than going to 100% all the time or running it really low. Accubattery for example will say you used about 0.2 battery cycles going from 35% to 80%, but 0.92 battery cycles going from 55% to maximum. They are probably just using that 40-80 rule to work it out, but assuming it is correct, you can see how much effect it has, being nearly 5x more battery cycles despite both being around a 50% charge up.
So charging it overnight will get it to maximum, which isn't great in terms of battery cycles. I have seen a couple of battery apps that I think can manage charging so that it notifies you at 80% to unplug it, but I don't think they can actually stop the charge at 80% if you leave it plugged in (althought I might be wrong on that). Again how much real difference it will make I don't really know, and it probably depends how long you plan on keeping the phone, 1 year then it shouldn't be too much of an issue, 2 years or more and I would probably at least try to keep it between 40-80% when possible.

Ha,
Been charging all my phones overnight.
Been using wireless charging since the note 3 and always please it on the charger when im next to it and not using my phone.
Never had a battery problem

Thanks everyone for their answers ..*let the overnight charging begin*

I used Ampere to check how much current was going to my phone when it was fully charged and it read 0.0 so I believe the phone cuts off the charging function when fully charged. As even on 100% without the "fully charged" portion on, it will still show trickling voltage.
Hope this helps. I also advise turning fast charging off at night just to be safe.

Fast battery drain from an year old device. Is there any way to slow charging speed?

So my 4a has been having fast battery drain since few months now. I remember it having very good battery life initially. However now it drains battery very fast.
This is also surprising since I keep brightness low due to me being sensitive to it.. and also keep the phone charged upto 80% capacity only as I read that it prolongs battery life.
One thing I could note is that the phone drains slower in the 80 - 100 % range if the phone gets fully charged occasionally.
Hence I have been suspecting the 'rapid' charging which is enabled by default on stock charger to be one cause.
Is there some way to enable slower charging like what happens in case of 'Adaptive charging' post 80% capacity? I hope that will lead to lesser wearing down of battery.

Don't use a compatible cable/charger and it'll change slowly. I don't think any PC I've connected to can do rapid charging, for example, and the cheap USB chargers I have definitely can't do it, only the one that came with the phone can do it.

It's more likely an app that drain your battery in background than your battery dying already. Quick charge and adaptive charge are made to not harm the battery.
Are you rooted? If yes, install Franco kernel manager app from playstore.
In first page you'll see your battery life estimation (from system) and clicking on live monitor go-to the processes tab.
Just like top cmd on Linux you'll see which process is active and how much cpu it use
For me as an exemple i realized that when I'm using YouTube music. The AdAway app goes crazy and drain my battery. And its something that's not shown on settings/battety tab.

Fast charging stresses the battery more than slow charging. That said I almost always fast charge. I expect 1-2 years of battery life on my N10+'s though.
Charging past 80% or discharging below 30% stresses the battery; Li's like frequent midrange power cycling.
Don't start charging below 72F, 82F or higher is best. High temp cut off is about 102F.
Never attempt to charge a battery colder than 40F!!!
Erratic fast charging is a sign of battery failure.
A rapid decline in capacity is another sign of a battery failure.
Any rear cover bulging ie battery swelling is a failure, replace asap.
Once a battery is below 80% of it's original capacity it's degraded and has reached the end of its service life, replace it.
Degraded Li's are more likely to fail which can easily destroy the phone.
If the phone is used heavily or is 2-3 years old, probably time to replace the battery. Just do it.
On most phones the cost is low.

Frankly don't have that much usage of my phone. Will give sometime to observing with non rapid charging. Will give this a try if that still persists.

UPDATE:
Started slow-er charging since few days now.. and I really feel that the battery performance has considerably improved
Also update to Android 12 since few days as well so not sure if that has a role to play though I don't think so

If it seems to work better... I don't see any difference on my N10+'s though. Run times are the same slow/fast charging.
Keep a close eye on it as erratic fast charging is a sign of battery failure... I have seen that
