Battery/Charging Queries - General Questions and Answers

Hello Friends, I have a few general queries.
What is the best method or practice to charge a cellphone battery? Should a user allow the device to completely run out of charge/power such that the device shuts down or switches off? Or should the user make it a point to charge the device once the battery level is between or depleting from 20% - 10%?
Also, does intermittent charging reduce the life span of the battery? The reason I ask this is because a cousin of mine has a habit of charging his cellphone (Sony Ericsson Xperia Mini Pro) every now and then. It does not seem to matter to him if the battery level is at 80% or 50%.
Personally, I have a Samsung Galaxy Note.
Thanking you in advance and awaiting your apt responses.
EDIT
I apologise if this thread is in the wrong section. Perhaps it belongs to the Questions and Answers sub-category of General Discussion. I urge my Superiors here to move it to the appropriate category/forum they deem fit.

My best experience when first getting a new phone is to do a full charge, then let the battery drain completely, and do another full charge with no intermittent taking the phone off of the charger, after a few times of doing this it should break the battery in.
Though some say this does nothing and is merely a myth - I like to think it's true as I have seen results.

I always do the charge, then full discharge, then full charge once on a new phone. From then on I don't pay attention.
I charge every night over night on my night stand. Then use phone throughout the day. If it is a particularly busy day I charge as needed whether that is the regular charger or cigarette lighter charger in the car.

Thank you icepally and 85gallon for your replies.
After I received my device, the very first time, I inserted the battery, powered it on and continued using it until the battery level was low (somewhere between 15% - 10%, although I cannot remember precisely ).
Should I have plugged the phone for charging immediately after inserting the battery or after powering it on?
Also, I did not follow a practice/order of complete 100% charge and complete 100% discharge.
Do any of you reckon what I have mentioned in the above 3 paragraphs will impact the battery life span of my device?
I apologise for my naive and paranoid queries. I am a noob!
Thank you once again for being patient with me.

You should charge any li-ion battery fully and then discharge completely without interruption as often as possible. Most ppl who complain the most fail to get this. This will give you longer charges by up to 25%

Hello Friends, I have installed BatterBatteryStats 1.0.0.0 on my Samsung Galaxy Note.
How do I use this application to serve me better? Also, is the said version dated or it is enough to be used on my device?
After installing the application, I am clueless about its functionality.
Thank you all once again for being patient with my stupidity.

Wipe Battery Stats, is it necessary?
Hello all, I would like to know if it is recommended that a Wipe Battery Stats be performed every time one flashes a different custom firmware and or a custom kernel?
There are suggestive opinions stating that such a practice allows the kernel to 'settle in' (for a lack of a better adjective), thus making a difference in battery life and performance.
Also, an acquaintance from my neighbourhood pointed me to the following article, http://lifehacker.com/5786717/get-b...ted-android-phone-by-wiping-its-battery-stats, which aroused the above query. My device is a Samsung Galaxy Note GT-N7000.
I have not followed any such acclaimed practice till date, and since I am naive and daft, I felt my query will be best answered by the experts on this wonderful community. Thank you all for your patience.

another easy question to ask.........first to do after buy a phone is to drain da battery first, do a hard drain and then charger a bit juz to make sure ur fone can be booted, boot ur fone n do a factory reset, drain it again, simply rebooting n shutting it down to drain it, after that, charger ur fone merely for 1 minute in off mode n boot again ur fone while charger still developing n make sure u close da sleep mode while charging until it fully charged. There u got ur fone fully regenerate da stat without using any software. then u can charger anytime,anywhere n anyplace as android hav excellent battery management.

post-mortem, thank you very much for the link to a technical reference. Upon reading it, I have learnt and thus become aware of three important aspects -
1] Never overcharge the battery.
2] Never discharge the battery completely or too low.
3] Power off the device and charge.
:good:
But is it absolutely compulsory to follow point number 3, and charge the device after powering it down?

I would say this is only a real issue if the device has high drain while charging. Like if you charge while on a call, or while using navigation. If you only do such things occasionally, I'd bet that the device will reach terminal utility in some other way, before the battery does.

For me, a new phone must be fully drained when used for the 1st time, and charge it for 5 hours.. It's always the common sayings for a lithium ion batteries.. and then after that you can charge the phone whether it's 20% 30%, etc.. then once a week fully drained the battery and charge..

Also. Overcharging will destroy battery integrity. Not like just charging overnight but if you just constantly always try to charge it and leave it charging when full for long periods of time. Its scientific.

Thank you post-mortem and apologies for the late response. The only activities I tend to perform while my device is charging is, either send text messages or chat via WhatsApp Messenger.

whodisname, thank you as well. I have always been cautious and have never kept my device charging overnight, and thanks to the informative guidelines provided in this thread, I will always remember never to overcharge the battery of my device.

Hello everyone.
When charging a device, either via AC mains using a travel adapter, or USB, is it a compulsory practice to use the stock original cable which doubles up as the data cable, to do so?
Just as there are after market premium batteries from the likes of Anker and Mugen, are there after market premium cables available as well? If there are, would a single after market premium cable be compatible across multiple, if not all devices?
The stock original cable of my Samsung Galaxy Note GT-N7000 has started malfunctioning. I contacted Samsung India's customer service to enquire about the availability of the said accessory, and upon the customer service agent's suggestion, I got in touch with the local Samsung authorised service centre, where an agent informed me, the cable will have to be ordered and it would take between 15 days to a month, to arrive at the local service centre.

1. yes
2. not that im aware of, but that doesn't mean there is not. most of them are junk though.
3. you could try ebay. sometimes people sell extra parts cheap, but i dont know how you would tell if it is authentic other than contacting the seller. many of the supposed oem stuff is just aftermarket china junk.

It really doesn't matter, as long as it's from a good brand. You're not going to damage anything if you use an LG cable on a Samsung phone. You're not going to damage anything if you use some crappy no-name cable, but you should stick with reputable names just for the assurance of longevity and steady connection (especially if you need it to connect to a computer). If you want to find an OEM Samsung cable, just find the cheapest/quickest to ship, and it'll work just fine.
The actual charger though, can be a different matter. ALWAYS go with a reputable charger, preferably the one that came with the device. But even the latter isn't all that important. Mainly you should worry about the charger malfunctioning and cooking your phone. But if you go with something name brand, it's extremely unlikely that you'll damage your battery.

The long shipping time is because you're requesting a specific part with a specific number. Just find yourself the quickest/cheapest Samsung, LG, Sony, Motorola, HTC, or other name brand cable, and you'll be just fine with it.

contrary to what planterz posted, on some phones, newer ones more predominantly, some will not charge properly or as quickly as possible if you don't use the proper factory cable. case and point is the lg g2 i have. fast charging doesn't work with crappy aftermarket or non lg cables.

@Planterz and @bweN diorD, thank you very much for your replies.
I have been charging my device alternately, sometimes using the stock cable of a BlackBerry Bold 9700, but mostly the stock cable of a Sony Xperia E (C1504).
:silly:
The Samsung OEM cable is available for purchase online at Mobile Fun India, http://in.mobilefun.com/46026-samsung-micro-usb-sync-charge-cable-black.htm. But, the shipping charge amounts to slightly above half the price of the OEM cable.
I have also looked at the Belkin MIXIT Micro-USB to USB ChargeSync Cable (F2CU012bt04), http://www.belkin.com/us/F2CU012-Belkin/p/P-F2CU012/, which I am very inclined to purchase.

Hello everyone.
How can the integrity of a Lithium Ion cellphone battery be tested? What is the apt 'hardware' method to do so? Also, would using an app (software interface) yield a convincingly accurate result?
The stock OEM battery of my device (Samsung Galaxy Note GT-N7000) has begun draining rapidly, and thus, I am keen on assessing its capacity related aspects and diagnosing its charge storing/retaining ability.
:fingers-crossed:
I await your valuable guidance.

[Q] how to run a phone without battery only by connecting charger

I think the question may be silly but I want to know the procedure for this. can I run the phone directly by connecting only charger and removing the battery...as I keep for downloads of movie over 3g it drains battery damn fast and if its kept charged the battery looses its power. so plz help me out.
I have been looking for this also, what I feel we have to do is like power the device from the battery port, I not sure how we would do this but a multi charger with the right voltage and amps might do it, I am sure there are repair centres that do this as they would not keep using battery's no scrap that I been to a few and they don't and when you send them your phone they ask your NOT to send the battery with the device, so there really must be away to power the device without the main battery but the phone would think the power source is from a battery.
If anyone as a idea how please drop a post.

besides physical limits power output from transformer/ "charger" is too high and will destroy the phone
"charger" because battery is really charged by the charging-circuits placed on phone mobo
It seems many people use old smartphones for their projects. I wonder how they make it?
I want to ask if it is possible to make a fake battery?

Please answer if anybody has knowledge about this
Yes
You should be able to remove your battery if you are plugfged into the mains charger and it shouldnt affect you phone peformance i dd this with my phone and i checked the performance with the SETCPU app and it was running brillantly i just set the app to run on full peformance when plugged into the mains and it was brillant.

Well, it's all about how the phone was build... My HTC Touch Cruise 09 are not working without the battery. I try to start the phone with battery, connect the charger and than remove it. The phone goes off. By mistake, I powered on an LG T300 without the battery, while the phone was connected with an USB cable to my computer. The phone started and worked fine.
So, take your own conclusion...
very helpful
this forum thread was helpful! thanks!
But this works with only some models not every model...is there any specific hardware to do so?
That's hardware related... If it was software related than developers would have done far back...
Any electronics guy/girl here?
Bump... thread into acitivity again... no answer yet. Like to know it as well.
Developers we have enough. But is there a person who has knowledge about electronics, and have an idea how to use , for example,
use a USB 5V without the battery. How to connect wires, what electronics components are needed?
The following website has a way to do it, but it's 12V and one of the components becomes very hot. I don't like that.

Help? Running a smartphone on USB power only would be awesome as a bettery is drained fast if you game, surf on the internet, etc.
My S6312 cannot operate without the battery, somehow the 3 connections have to be connected. But how?
Are the connections the same for example the S7275R?

Huawei U8825D Could Be Run without battery by Connecting with a Charger
To my astonishment, with battery removed, Huawei U8825D could be turned on and operated normally with the charger plugged in. I came across this thread as I was wondering if there are tweaks that could be applied to other phone models to enable this function.
I' not sure if this will help but no harm in posting it so may some one can find the best mod I used a similar trick my symbain and gess it will work fine with any other phone but am not responsible for any side effects or any thing like that...
Recwirment are a battery with the same voltage of your phone ana two wires. Attach the (+) born of battery with (+) born phone same thing for (-) and put the charger and play with your phone as much as possible tested on n8 symbain but not android so be careful about it

I wonder if phones can not work with no battery, how it can be called an accesory. Because accesory is "1. clothing that is worn or carried, but not part of your main clothing, 2. a supplementary component that improves capability". Samsung says battery is accesory therefore changing battery four times can not provide repayment or changing phone procedure. Have they a right like this
It should work by taking the protection circuitry from an old battery and take a power bank that uses a lithium cell and connect the + & - of the power bank to the + & - of the battery circuitry.
This way it should trick the phone into thinking it has a fully charged battery installed, plus giving the extra overcurrent protection from both boards.
I know its kinda late, but I am searching for a topic and this is as close as I am getting to it. So here is my question. I have an LGV10 from Verizon. I am rooted but have no custom recovery. (you can look up those threads about all of that) I was curious about seeing if I could sort of hot swap the batteries by plugging it in and changing them. The phone appears to run fine off the charger alone, but a message comes up on the screen saying battery removed. Shutting down. Is there a way to get around that?
need powersupply with right voltage and ampere
afaik you need a powersupply to do that.
check the battery voltage and ampere.
adjust the power supply to the same volt and ampere.
connect + and - pin, power up the power supply and turn on your phones.
power supply tools for mobilephones arent cheap.
alernatively,
if you have a technician friend, perhaps you can ask him to make a non dynamic power supply nor electric adapter with certain voltage and ampere
For all those still curious on how to run a phone with no battery
Add watch?v=f0IuBld2lzA[/url] at the end of youtube. I can't post links yet. Basically you cut off the end of your USB cable and connect it directly to the leads on the phone that battery normally connects to. Kind of like a universal charger being used direclty on the phone.
I got an idea

Well battery have some internal registance .
Maybe if you connect a small register between tow nodes of power output of phone, you can possibly emulate presence of battery.
But if it doesn't work then you will facing some circuit failure. All the best . Let us know your result

[Q] Honestly, is the Skyrocket a "good" phone?

So here is the deal... I have been a Verizon customer for years, and I am just sick and tired of them jerking me around and upping their rates, taking away unlimited data, taking away early upgrades, etc. So I am thinking of jumping ship and going to Net10. I am currently using the HTC Rezound which seems to be roughly roughly equivalent to the Skyrocket (Yes, I know I will not get true 4G/LTE on Net10, only HSPA+). I can get a new, sealed in the box Galaxy S2 Skyrocket (SGH-i727) for about $210 on eBay.
So where I am going with this, knowing Samsung has had quality models and, well, lets just say questionable models, how is the Skyrocket? Is it solid and relatively problem free? How is battery life, is it easy to unlock, root, ROM, return to stock, etc? Has anyone used this on Net10/StraightTalk?
So basically I am just looking for people's opinion of the phone in general, from a heavy phone users perspective... My other alternative's at this time are a new unlocked HTC Vivid which I can get new for just under $200, or just suck it up and grab a Nexus 4 from Google, although the $350+tax and shipping for the 16GB model would hurt, a lot, right now.
Thoughts?
I, along with most other power users here in the skyrocket forum will tell you that this is a great device. Rooting, rom-ing, and general modifications are a breeze as long as you read the stickies and have an ounce of common sense. Battery life is subjective to individual use, but I generally get around 12-15 hours with 3-5 hours screen on time. This can be extended significantly with a nexus extended battery and a minor modification (see accessories section for details). Hardware wise it it solid. The only common issue we've really seen is the power button failing for some users, I've had mine since it was released though with no issue so far. We have official support for CM, Slim Bean, PACMAN, and Avatar ROM (maybe more but I can't remember off hand), and ports or unofficial builds of just about everything else you'd want. Also, 4.3 is being worked on hard by our fine devs, and it seems that external speaker audio is the only thing preventing a beta release for most roms at the moment.
The community is, for the most part, knowledgeable and willing to assist with any problems you have as long as you attempted to do your homework first.
Any other questions, let me know. Otherwise, I'll extend a tentative welcome to the Skyrocket family.

One issue bothers me a lot. I cannot use the phone for navigation for more than 2 hours even with car charger connected. In about 2 hours, it drains out fully. My latest theory is that after about 30 mins of charging, the battery starts heating up, and so it stops charging.

I am not 100% sure in terms of the amperage. But I tried with a car charger capable of charging a laptop, using the wall charger and cable which came with the phone. I was sitting in the passenger seat, phone was in my lap (not mounted in windshield) and Google Maps was running in navigation mode. For the first 15 minutes or so, I saw that the phone was charging. The charge level increased by 1% or 2%. After I think 20 minutes, it stopped charging. CPU-Z app was showing battery status as
health: over heated or heated (don't remember clearly the text)
power source: connected
status: not charging or discharing
Phone's back was very hot. I unplugged the USB cable and connected it back, and it started charging again! I waited for it to cool down, removed the phone case, repeated this and got the same result.
This is why I believe the phone is doing something to protect it from over heating. I am not sure though.
Well, I placed my order and should have my Skyrocket by the end of the week, and already have my Net10 SIM and $50 Unlimited card! So basically I am saying you will see more of me around here in the future. Thanks again bps119!

Amperage is important son too little it will discharge, I think it will limit if too much. Nav can cause some heat for some of these guys but I've never heard of it getting that high my guess is something was wrong.

I have gotten my last few chargers at Sam's Club, they are about $10, and are rated at [email protected]
In an older phone I had a similar issue where my phone would overheat and not charge properly, once I got a new charger I cut the end off the old one and read the voltage with a meter, it was putting out almost 7.1v (should be 4.75-5.25vDC for USB 1.0-2.0 standard, and 5.25-5.75vDC for USB 3.0), pretty sure that is what caused it... cheap components equals cheap quality and flaws. Current rating should be irrelevant, as long as it meets the devices minimum requirements (most modern phones are [email protected]), even if a charger is rated at 2, 3, or even 5 amps, the device should not draw more than it can handle. Current is drawn, not pushed, a device will draw the needed current at the expected voltage, you can't really "over-current" a device by using a power source that is rated at the proper voltage but a higher current. Similar instance can occur by using a charger that has too low of a current rating, the device will try to draw more current than the adapter is rated at and the adapter will eventually fail or fall out of specifications.
Some other good chargers are by Anker, PowerGen, or RAVPower, and of course a Samsung branded adapter will work well, most all of these can be purchased for $8-$15 on Amazon. If the adapter is not rated with a current rating, then skip it, it is probably only 600ma-750ma and will be more headache than it's worth in the long run.

Current rating should be irrelevant, as long as it meets the devices minimum requirements (most modern phones are [email protected]), even if a charger is rated at 2, 3, or even 5 amps, the device should not draw more than it can handle. Current is drawn, not pushed, a device will draw the needed current at the expected voltage, you can't really "over-current" a device by using a power source that is rated at the proper voltage but a higher current. Similar instance can occur by using a charger that has too low of a current rating, the device will try to draw more current than the adapter is rated at and the adapter will eventually fail or fall out of specifications.
Some other good chargers are by Anker, PowerGen, or RAVPower, and of course a Samsung branded adapter will work well, most all of these can be purchased for $8-$15 on Amazon. If the adapter is not rated with a current rating, then skip it, it is probably only 600ma-750ma and will be more headache than it's worth in the long run.

Just like to say great. I love my skyrocket. Over clocked at 1.78ghz and 320mhz gpu . great performance. Also with nexus extended battery for $6.50 at sprint. I have no reason to buy another phone. Welcome to the skyrocket community.

I have an HTC Sensation and today I rooted my friend's Skyrocket. I must say, EVERYTHING about the Skyrocket amazed me in terms of performance, ease of use, and quality even though it's very similar in hardware specs to my own phone (both are MSM8x60). Rooting the phone only took about 3 minutes (installed TWRP; there was no locked-bootloader crap to deal with) and the colors on the touchscreen are wonderful, not to mention the sensitivity of the screen is great as well. The Skyrocket has official CM10.1 going for it so I installed that and it's fantastic; everything runs perfectly. Even while using the kernel included in CM10.1 the device was very fast but when I overclocked it, the performance blew me away, not to mention the phone didn't heat up at all (even while gaming!); compared to that, my HTC hits 70°C while gaming on CM10.1 at stock CPU/GPU frequencies. Rooting my friend's Skyrocket today has thoroughly convinced me to never buy an HTC again Also, the Skyrocket has great dev support seeing as how CM10.1 is official for it.
TL;DR: The Skyrocket is way better than your HTC and, in terms of development, it's not gonna die any time soon.

One issue bothers me a lot. I cannot use the phone for navigation for more than 2 hours even with car charger connected. In about 2 hours, it drains out fully. My latest theory is that after about 30 mins of charging, the battery starts heating up, and so it stops charging.

The Skyrocket (and several other Samsung phones) need special "type 2" chargers. Apple charges are type 6, so if it says compatible with Apple, don't use it as it may not work. If the two center pins on the USB port doesn't have a 50 ohm resistor across them (or not shorted) , the Skyrocket will only draw 350 mA. Samsung and older Curve BlackBerry chargers have the resistor. At 350 mA, the phone draws more than the charger is providing, and the charger circuitry heats up trying to keep up with demand.
Jrockttu has a great thread under General called "Fix your Skyrockets battery life"
I've MOD'd all of my chargers, now my phone is happy with the screen on all day while driving and it stays charged, or charges slowly...

I recently got rid of my Skyrocket. It was a good device, but a bad phone. The built-in microphone is terrible, people were always screaming that they couldn't hear me unless I used a headset. The signal was poor too, and I would often not receive calls (with no missed call notification or anything).
The Cyanogenmod support is good, and for an old device it runs plenty smooth and plays all the games I throw at it. So it's not bad in that regard. But the actual phone functionality was a real problem for me.

Well, my Skyrocket arrived, looked great and appeared to be "new"... I fired it up and everything looked fine, but it wouldn't recognize the SIM card, just said "NO SIM INSTALLED - EMERGENCY CALLING ONLY" and wouldn't let me do anything in mobile networks at all (said something about must be registered to a network first), so I popped in an actual AT&T SIM, same result, and both SIM cards work in my old HTC Aria. Called the guy I bought it from on eBay, have to send it back and he will send me another new one. Hope this isn't a bad omen.
That sucks man, kinda takes the excitement out of getting the new phone. Oh well, forget it ever happened and hope that it was just a fluke.

Honestly, you'll love the skyrocket. I've had mine for a little over a year and a half and it's more up-to-date than my girlfriend's s3. It's faster and lasts longer on battery as well. Although her s3 isn't rooted, being a newer device, you would think it would work better than mine. Not the case!
If you're trying to unlock your phone, there is an unlocking thread you could check out, although I'm not on touchwiz so I couldn't do it, others have had success with it so you shouldn't have to worry there. We're a great community, just like we've been when I first rooted a year and a half ago. Enjoy!

[Q] Differences between a BG58100 & GI39100 Battery? [ANSWERED]

Short but powerful,
Without all the blablabla straight to the point. I got ?fooled? by a phone company 's expert(?) who told me this was not going to do any damage to my phone, and refused me to give me my money back after i found out that the battery was not good(the same as OEM z710e voltage ratings) when i came home.
I have a z710e, it came out of the factory in 2011. Original battery specifications:
m/n BG58100 p/n 35H00150-02M (3.7VDC 5.62Whr 1520mah)
The battery triple checked by "Expert" and sold by him is a:
m/n BI39100 p/n 35H00170-01M (3.8VDC 6.08Whr 1600mah)
My phone model: z710e (PG58130) original battery p/n: 35H00150-02M from 2011.
Next time I'll check this stuff myself and don't let those people do it for me. They either don't have any good batteries for this model and just sell the one that actually over volts your phone. Or other batteries and so had in his mind to sell me this and don't care about it, like "oh well who the heck cares, this person will never find out and will return to me when his phones is death". Well I'm pretty sure that this will not make my phone last any longer than a year / half a year or less! And i still need it for a year or longer if possible.
Feel free to reply, but only if you know that what you are telling is 100% correct. Please avoid non-valid information or answers, thanks :good:
I am not a pro either but this just doesn't seem to be correct. Feel free to correct me, if i made any mistakes.
https://www.google.co.uk/?#q=35H00170-01M+compatibility
If you don't understand my actual question, then I'm deeply sorry. Often my stories are not so easy to understand duo to my bad English.
The question in a nutshell is simply : Will this higher end battery do damage to the phone and is my story right, i mean is this battery not compatible with my model because it can do damage duo to over volting the ma inboard/soc (because of higher battery output ratings?)

First of all you should search a little bit more to see that the same battery (35H00170-01M) is offered by numerous companies as a replacement battery for various phone models (Titan, Vivid, z710e...) just like the battery from your phone (35H00150-02M) is offered for the same models.
Then, you can find the same battery (35H00170-01M) offered with different voltages, both 3.7V and 3.8V, and the difference of 0.1V will not harm your phone, cause, you can see it yourself, voltage rating for the original phone charger is 5V and it doesn't harm your phone.
And the last, the other data you got for the battery (Whr and mah) mean only that you have battery that should last longer than the original one you have.
I hope I helped...

It indeed is, but i have really bad experience with replacement batteries. And those small 'voltage increases'. They end up to die quicker a lot quicker in my personal experience. And i think it is also the reason why, many sellers don't include my model in the compatibility list.The 3.8VDC 6.08whr version is meant for the XL and titan version witch is actually indeed the same but +300mhz overclocked.

To be honest I have some cheap s**t called Hinorx Extended Battery that's 1200mah (don't know what's extended there but that's what I got when I ordered regular replacement battery for Sensation) and it works really well, can go up to 25-30h with 2h of screen, lots of wifi (ARHD 7.3 with 1,5MHz o/c).
Don't worry about 0.1V, it means nothing. And for life of battery I hope you got warranty...

It don't has warranty. But it's oke. It is a OEM battery they said. Btw it works fine, only had to use another charger with a output of 1.5a. It would not charge otherwise. But well, lets see how long it keeps working.
Haha it seems to not work charging for 5 hours now and still 0% cannot go in cwm recovery and when it starts it will reboot and orange/green led will blink again. I tried to reboot it several times, tried to clean/bend the pins and all the other tips from XDA forum seasrch results and nothing seems to work.. Great =(

Yes i did but it got extremly hot so i switched back to the stock charger. And it actually should be fine? +0.1 volt doesn't matter?
The battery does not hold charge at all. It turns on battery level is 0% and will reboot and do orange/green led indication for as long as you keep it in the charger. When you get it out of the charger and turn it on it will go off as soon as android is loaded up intro the pincode screen. Guy at the store told me the led indication meant that the bettery is at an extremly low level of power and that it just needs to charge some more.
Well i have been charging it for like +5 hours now for sure. Using the OEM charger rated at 5VDC 1A. It is not the cable or faulty charger. If i test the output or on my tablet it works just fine. And with the old battery i'm able to charge it, but the old battery is dead, it does not hold load properly anymore. It drops a lot of times from 80% to 1% in like maybe 30 minutes of usage.
Also when using the GI39100 i cannot get intro adb or recovery..

Faulty battery. It's not about volts, it's about bad battery.
You should require replacement or reimbursement.

It is the second brand new battery the guy in the store put intro it.
Both did the same, it just doens't work.
1. Does not turn on (sometimes when lucky)
2. Holds no charge
I did
1. Wipe battery stats (in the end, like 5 minutes ago from writting. It took me half an hour to get the phone booting while charging)
2. The phone started only twice, now it does nothing anymore (with this new bat).
Also the battery info was all wrong.
When i checked the 1st time when i got it on i went to settings > about the phone > status > batterystatus it did show me(i left it nearly 3 hours like this and still 0%):
- Batterystatus: Unknown <----------------- Before battery stat wipe, after wipe still the same, no power on.
- Battery level: 0% <----------------- Before battery stat wipe, after wipe still the same, no power on.
While it should look like this!
- Battery is being discharged (when not charging)
- Battery level: 93% (old poor battery meanwhile after so much testing already full again)
When i put the old battery in place it works without problems. When i put the new one in it doesn't + battery stats are not even readed by android itself and recovery menu stated a warning. "Warning phone is under-volted" or some message like that. And the LED indicator flash in an unusual way (orange/green) this probably is an error code. Well, complete nonsense because i use the same charger. And the XL version has the same 1A charger, so this makes no sense. The battery is just not compatible.
The battery has been charging for almost 13 hours now. And still 0% + orange/green led flashes.
I have no tools here i had to imprevise with crap, gluetape and a doorbell to get a cracky 5 dollar multimeter working, LoL.
here is the bat output;
a 0.08 v 20 3.52v hv 750 0.07 hv 200 06.8 with other words it should be fine to run and maybe get 50% battery level. But it is still z3r0~ when i put it in my phone.
Topic prefix can be set to [ANSWERED]. The m/n BI39100 p/n 35H00170-01M battery works just fine in the z710e. Confirmed to work, even with 0.1v increase (does not produce more heat or instability, like some cheap fake batteries do without protection IC xD)
I went back to the store they gave me another battery and it instantly worked. So i had two faulty batteries. Lucky me again haha....
Probably or the store where i got it from does not test bats and throws them intro one big box or just very very unlucky.
The battery stats now work, no warning in recovery menu and no orange/green flashing in the led indication.
So if somebody has the same issue as me, your battery is 100% sure faulty. And you should toss it back to the re-seller for warranty or if you purchased the parts loose RMA it.
Get or an good alternative non-oem brand like anker. That is sure to be safe and good of quality. And never use fake chargers from like cheap Chinese tabs or phones. Often they have terrible output and this can badly damage your battery/phone because the output might not be stable enough and drops and increases a lot of times, either using a 2A charger does not make any sense at all. It will go just as fast as a 1A charger because the limit is 1A through(in most phones some can have other ratings). Only thing that can damage your phone/battery is if you go over the 5VDC. More volts = more heat = less lifespan. Amps are taken by the device and volts are given.
Confused
The new battery i have now is a BI39100 35H00186-00M. The 35H00170-01M does not seem to work in a PG58130 z710e or i had two faulty batteries... ?

Non-original chargers suddenly very slow.

Phone: Lenovo P2
All problems occurred while charging overnight, say 7-8 hours of charging time.
Normal charger completely charges the phone, no problem it seems. Output 5.2V/2A to 12V/2A, it's a fast charger.
Non lenovo charger, an Oppo Vooc charger, rated at 5V/4.5A
Other chargers I tried are rated at like 5V/1.5A
Both charge my phone 20-30% overnight.
All other chargers used to work fine and fast.
Anyone know what could be the cause of this? It's bugging me, and i've got about one month left on my warranty.. (but the repair centre lenovo uses in my country is also the worst ever)

Thank you for the tip, but in this case I don't need another charger or anything. It's just that all the other chargers became slowly at some point. That's the problem. (and the solution wouldn't be to get another charger, I still have the original one, I just want to be able to charge normally on all chargers)

That sounds like some kind of software running in the background causing excessive battery drain.
Here are a few possible causes:
1) installing stock updates without wiping the cache partition after the update. Failing to wipe can make a lot of things buggy.
2) installing too many social media apps, these run constantly checking for updates and notifications, causing excessive battery drain(to the point that the battery barely charges slowly).
3) a failing battery can cause a slow charge.

Best way to protect/ensure longer lasting phone and battery with Android?

Just bought a Galaxy 21 FE edition (whatever that means..) and since the phone is fresh and new, along with the charger, I was curious as to what are some of the best ways to preserve things like battery life, charge ports, cables for the charger https://9apps.ooo/, just general care that people do that may go over the top to protect and keep their phone running in top shape for longer, thanks

well, simple. i got a couple of rules :
1. always charge it in ultra/maximum power saving mode. charges the fastest, it does not heats up at all
1b. dont play games or use anything battery strenuous while charging.
2. use a magnetic cable with a magnetic port. the magnetic port closes the usb type c port from my phone, thus no dust can set in the port. trust me, i had removed quite a bit of dust from some of my previous phones.
3. keep the phone internal storage as light as ever. dont fill it with junk, use the microsd card for that.
3+ original battery and counting. still holds for 2 days. my oldest device, a Transformer EEE Prime (11 years old) still holds a charge and can get through a day.

Correct: Each battery automatically discharges itself over the time continuously by a certain percentage ( ~10% per month ). This process can be decelerated by storing the battery (the phone) in the refrigerator.
Stephanuscoontz said:
1. continuously charge it in ultra/greatest power saving mode. charges the quickest, it doesn't warms up by any means
1b. dont mess around or use anything battery exhausting while at the same time charging.
2. utilize an attractive link with an attractive port. the attractive port shuts the usb type c port from my telephone, in this way no residue can set in the port. trust me, I had eliminated a lot of residue from a portion of my past telephones.
3. keep the telephone inward capacity as light as could be expected. dont fill it with garbage, utilize the microsd card for that.
3+ unique battery and then some. still holds for 2 days. my most seasoned gadget, a Transformer EEE Prime (11 years of age) actually holds a charge and can get past daily.
