Shocking battery capacity left after 2 years of usage - ZTE Axon 7 Guides, News, & Discussion

My phone have 3 hours SOT on performance mode, and 3.5 hours SOT on smart battery mode.
I am on stock (7.1) with greentify and jovoc battery tweak.
Lately, I do a battery check using USB capacity tester (KEWEISI).
Charging my phone from 0% to 100%.
And the result is 1580 mhA (
This explains two facts:
1. While so many people confirm that Axon 7 have good battery, and somes complain about terrible battery recently.
2. Accu​Battery is not really "accurate" tool to check your battery (the app report that the phone have 2700 mhA left).
Still, I wonder what had toasted my battery so much - quick charging ? overnight charging?
Beside, I notice shadow on navigation bar area (on full white screen, the navigation bar area is more white, the rest is little yellow
______
Edited: After replaced the battery, SOT is 6 hours

My two previous HTC phones had huge battery issues after the first year. I treated them bad in this regard, charging very often (rarely let them go under 50%), and I let them charge over night.
I am doing a better job with my Axon now, I never let it charge over night, I always keep it between 20% - 80%, and I avoid using quick charge if possible (I prefer charging it at my PC, slow and steady) quick charge is causing the battery to heat a bit and that is causing a lot of damage over time.
Indeed 3H SOT is very bad, even with my HTC One M9 that was abused pretty badly in this regard I had 5 - 6 hours SOT, and the battery on it was lower capacity to begin with.
And about the yellow spot on screen, my M9 had that too, just a bit under the notification bar on the right side. I assume that there's something in that area that heats up during charging? I noticed that if the phone was cool that spot on the screen was barely noticeable, and when the phone was charging and hot, the spot would become very dark and noticeable.

As @rzarectha I use the same tricks (20/85 %) and slow USB charge (If I've got the time) and my SOT after 19 months is pretty good.

@rzarectha @JLLE , what is your SOT?
I dont expect the SOT to be great at first because of 2k screen. If the axon battery is that good, I may replace the battery.

It depends, but with a medium-heavy use mostly I am over 5/6 hours (with a good 4g connection).

accubattery estimates 7:45 with the battery at 100%

It depends of the way you use your smartphone and of how good is your connection. But if I use my Axon lightly, with the night mode activated when I sleep, I can hold it about 1.5 day without a charge.

I purchased mine from this seller on eBay and it's been fine. https://www.ebay.com/itm/New-Batter...TE-A-A2017U-/352253103538?hash=item5203ebcdb2 Use this video as a guide https://www.youtube.com/watch?v=wqivSM0NFsc&t=77s. It took me around 40 minutes start to finish.

Your battery is a consumable and it can be replaced. Take advantage of this and replace it.
Fact is there is literally nothing you can do to prolong the life of such item as a battery, that is still a mystery to the modern science.

@tamahouse, today, after your first post, I've tested my phone by a complete discharge/charge round with Accubattery and I can confirm you that the results are not reliable. The estimated capacity of the battery is completely wrong.
Envoyé de mon ZTE A2017G en utilisant Tapatalk

@tamahouse @JLLE May I ask how you guys are using Accubattery? I tested with someone else w/ an USB thingy and it reported about 50 mA less which is much better than what you're saying.
To get a good reading from Accubattery you have to make at least 3 readings with the phone on standby. If you use it while it's charging, the phone will use current, so the current that gets to the battery is way less, and you get weird readings.
I've used it thrice and I got 2400 twice and 2350 the last time. You can see clear outliers on the graph when you charge it with the screen on

As I said, I've used Accubattery since this morning. I've made several readings and here is the result for battery capacity.

@Choose an username... About accubattery, I think the quick charging make the estimate less accurate. So I will do slow charging on both app and usb thing, and post result latter

In the video, when attach the back with the screen, the guy dont use any kind of glue, he only use 3M tape to stick the grills to the phone. What did you use to reseal the phone? Glue or 3M tape or just close the phone like that?

The body of the phone snaps together with no glue. I used double sided tape, 3mm wide , it is doing a great job holding the grills on.

How did your SOT change?
I'm on the she honestly, the battery life right now is very upsetting, I want to buy a Xiaomi budget phone just because I won't have this kind of problems. But my last chance would be changing battery.

In my case the phone went from a little below 3 hours to 5.45 SOT. It was at 58% capacity when I installed the new cell and now it's reading 97% with Accubattery.

Higher capacity battery

This is the stock battery, EP500 Li-Polymer 1200mAh
Code:
http://www.sonyericsson.com/cws/products/accessories/overview/ep500
No memory effect, can charge anytime, full charge obtained on around 3 hours via PC USB port.
Compatibility : Vivaz, Vivaz pro, Xperia mini/pro, Xperia X8
This is the best choice I can find on an alternative battery, claimed to be 2430mAh.
Code:
http://cgi.ebay.com/130561150352
Double the capacity, which I believe should at least provide more juice. Planning to buy, but I suppose since most phones we have are new, we better see what the fully optimal EP500 can do first.
Any other choice and experiences, let us know.
---
UPDATE : Based on feedbacks of that battery brand, its highly possible that higher capacity battery is not really accurate. There is no direct feedback on the EP500 replica model though, that remains to be found out. In my opinion, for best case, its high chance its just like the stock battery performance.
---
For my personal use, I bought an Energizer AP650.

Energizer AP650MC Output : DC5V--700mA
On AP650 fully charged (charging LED off) plugged on an off SK17i (died to lack of batt), it will take around 25 mins to drain the AP650 into the SK17i while its turned on, standby idle.
SK17i was able to get 28% charge. From this data, I can say the AP650 can charge the SK17i at the rate of 1% per minute for max of 28 minutes. This means the whole charge of the AP650 can bump the standby (idle) time for at least 12 hours.
I will add more data when I find something of value. Will take actual picture with the phone also.
update: i changed phone already, went back to xperia arc but still sometimes use the energizer.
the alternative battery, is it still have same size with the stock battery ?
from the picture it looks like the same size, else they should provide a new back cover.
Mugenpowerbattery
As it is the same battery like in the SE x8, i suggest to try out this one from Mugenpower:
http://www.mugen-power-batteries.co...nded-battery-for-sony-ericsson-xperia-x8.html
But you only gain +100 mah.
I tried a battery from Mugenpower on my older phone and the quality is good.
But for that price I don't think I am going to buy this one only to gain a little bit more power.
That is a little steep for me. In the 20 range is find but in the 40's for 100 mah more just won't do.
I was looking also on ebay at the 2000 something mah but could you really fit that power capacity in same size battery? Please post any feeds if tested
Sent from my SK17i using XDA App
so.. anyone has tried it ?
i'm really interested on 2430mAh
i hope the written specs will not lie
Once I begin to feel the itch for the need of longer life I will buy that. But so far for now, I still need to get the feel of the stock batt so we'll have better comparison when time comes. Unless someone here really buys ahead :$
Sent from my SK17i using Tapatalk
Packing almost more than the double mAh in the same size seems pretty unrealistic. I think its fake.
I mostly fear that it could damage my phone. Have read that cheap batteries can explode or damage the phone and I have this phone only for a week now and would like to keep it though.
Sent from my SK17i using XDA App
I had the same thoughts and reservations. But not really to the point that it damages and explodes. Its the authenticity of the claimed capacity is the question.

i agree, you would be shooting in the dark when purchasing this but someone could make the 1st step.
we can see if our battery performance increase over time or i propose donating to the cause, to a credible member and buy one to test it out. just a thought
I'm willing to buy, try and inform you all. Let me settle with the stock batt first if I would need higher capacity, unless someone here buys before me. I would think the capacity may not be necessarily true, but since its double capacity then perhaps we get at least 50% of what it offers right (ie. 25% more juice) compared to stock battery in its worst case, and in that case even it may be acceptable for the price point?
my feel : it seems after some days of getting the hang of the phone battery life, it looks like if doing nothing with the phone at all sit it standby, it easily reaches 2 days of life and can even go for a few hours more but i doubt it will reach 3 days. however, once normally using the phone like browsing wifi, tinkering, etc. it definitely can only max out in less than 2 days. if doing more browsing and use calls, 3G, in one day or less it likely will finish the charge. if straight wifi internet browsing, i doubt this will reach 7 hours max.
perhaps need more cycle charging as phone barely a week old. any other experiences?
Hello guys, i asked mugenpower if they would make a higher capacity battery for the Xperia Mini Pro.
They said that there wont be a battery for the Xperia Mini Pro in the near Future and we have to Stick with the 1300 mAh they are offering for the x8.
Sent from my SK17i using XDA App
From my latest feel on the stock battery, upon regular use it will only really last 2 days tops. If used a bit more say browsing over wifi, video watching, calling, browsing over 3G, then it would only last like only ~42 hours.
However, I am thinking about an another alternative to the higher capacity battery in question on the first post, yes it is cheap but it is highly likely that it is an impossibility to fit into the size even 50% additional more power into the battery of the same size. Therefore high chance it is fake.
The other alternative I think is just get usual USB portable chargers, the likes of Energizer XPAL. I also noticed the phone charges really fast (ie. 2+ hrs) due to the small battery, so perhaps useful to have it charge even in your bag while commuting hmm?
The phone is compact enough, so bringing an an additional power which can also serve the purpose for other gadgets as well may be an option.
What do you think?
I personally would use the portable charger. I've had horrible experiences with fake batteries, most of the time they don't even last half as long as the OEMs.
Stop, don't buy the 'gold' battery from that seller!
The capacities are fake, I got ripped off myself, the batteries are just normal capacity clones. Look carefully at the negative feedback.
Thanks paul-home. Yes I thoroughly read the feedbacks but the reason I posted that item cos its the only higher capacity batt available. I will edit the 1st post to put a disclaimer.
Anyway, what I am trying to do is just maximize the stock batt, I noticed it lasted really longer when I let it sit on the charger even if it is 100%. The battery status stays at 100% for 6 hours when left on standby. In any case, I am firming my investigation and will recalibrate the battery stats on phone and see how it really goes.
Added data about the Energizer AP650 extended microUSB portable charger on the first post.
Too bad it is fake.
I could use more juice cause i have the wi-fi turned on 24/7.
Would be cool if they made a higher capacity that has the battery and back cover all in one
Like this

For the mini pro.
It would also make the phone even thicker
Sent from my SK17i using XDA App
I really like the battery for this. Charges up really quick and lasts (for me) the full day. I think a better alternative to buying a higher-capacity battery would be to just buy a second official battery and keep it in your watch pocket (the little pocket on the front-right of your jeans) in case of emergencies.

3030 MAh Gold Battery

Hey guys,
Some of you might've seen this on the N7000 threads,
This is to confirm that the same battery is sold to Canada on Ebay, and it works pretty well on the i717.
The battery is called the "3030mAH High Capacity Gold Battery"

I do not have the test results yet from Battery Monitor Widget, because I don't really know how to do a full MAh test. Maybe someone can enlighten me on this.
Through everyday use however, it does seem to give me an extra 10-15% on the battery (which is around one hour for me).
For those who are interested, order it from this Ebayer:
http://www.ebay.com/itm/270942481442?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Ps. The Charger is SLOW though, I usually use it on the other batteries overnight.
Have you had a chance to get numbers from battery widget?

I have this one and t he 3080 one. Both work ok- not much more lasting than stock. I get 35% by end of the day remaining with moderate use, push email, 10 widgets, and 14 alarms.
I have the 3000mah version from these guys and these are just 2500mah batteries repackaged. I thought that I was getting more battery life too at first, that's mostly because you are trying to justify the purchase subconsciously, but they aren't any bigger and are actually lighter than the stock battery
They do seem like good quality batteries, just not any longer lasting than stock unfortunately.
If it were possible to get a longer lasting battery in this phone that was the same size as the 2500mah one you can be assured Samsung would be selling it as an accessory for $50, people would gladly pay for it... Samsung wouldn't miss out on making extra money on accessories...

If it truly is a larger battery then it should take at least 30 minutes longer (using the 1 amp wall charger) to charge from dead to full.... But I found that my charge times didn't change any appreciable amount, so the capacity isn't any different...
Here is some times taken when i first received the battery.

I don't know of this 3000 mAH battery that you are talking about, but I peeled the covering sticker from the Gold battery in the OP, and it doesn't have any markings indicating the capacity.

No not yet, haven't found the procedure to measure actual mAH in the battery yet. I have tried charging to 100% and draining it to 1%, but it doesn't show the information automatically.
so its not really 3030mah ?????????? thats been proven?

It doesn't take any longer to charge from empty than the stock battery does, so Its not any larger. My charge times were within 10 minutes of each other when comparing to stock.
Ebay batteries that are the exact same dimensions as stock but claim to deliver more capacity than the stock battery are pretty much always lying about capacity. Its all marketing. If the battery was heavier than stock I might say it could deliver more capacity, but they are usually lighter.
There is an app on the market called battery drain...
https://play.google.com/store/apps/...fender&feature=nav_result#?t=W251bGwsMSwyLDNd
Be careful using this, it will drain the battery VERY fast, potentially heating up the battery to beyond safe temparatures. DONT SELECT EVERY OPTION!!!
Here are the options you can select to have it do all at once.
-Turns on Permanent Vibration
-Enables Wifi Send Data
-Constantly Max Loads CPU
-Sets Screen Brightness to Maximum
-Enables GPS Location Services and Constantly asks Device to Refresh Position
-Turns on Camera Flash
-Turns on Bluetooth and Constantly Scans for New Devices
I would also grab battery monitor widget pro by 3C (the paid version is $4) or another battery app that has detailed logging.
https://play.google.com/store/apps/...ult#?t=W251bGwsMSwyLDEsImNjYzcxLmJtdy5wcm8iXQ..
Consistency is the key, what I would do is power down the phone and let the battery completely charge (use the volume rockers to turn the screen occasionally to see the battery charge level, its fully charged when there is a 100% shown inside the green battery).
Set the battery logging app and the battery drain apps either on the lockscreen if you have something like widget locker or set them on the first homescreen that appears on an initial boot so you can access them quickly.
Then unplug the phone, note the current time (open the clock on your PC for seconds), power the phone up, wait a set amount of time (say 1 minute from when you initially turn the phone on) and launch the battery drain app, turn on maybe 4-5 of the options (dont use all of them, you dont want to damage the battery), say max screen brightness, camera flash, wifi, bluetooth, & GPS and wait til the battery dies and note the time when it dies (shouldnt take more than 1 hour).
You can test each battery this way (make sure you pick the same options in the battery drain app) and if you have an app doing battery logging, you can pull up the stats after the phone dies and you plug in the charger to reboot it.
Its also key that nothing changes (dont install any new apps or remove any apps) between testing. What most testers do is factory reset the phone, leave all the settings at stock and install only the apps they need for testing. This might be a bit extreme, the key tho is to have consistency.
Using both batteries and testing them in this fashion would give more information rather than anecdotal. However, I can understand that it is a time consuming process.

Battery replacement? - 10/11/15

Hi Xda, I need to replace my battery because I bought my phone from a man who destroyed it with something like 1300 charging cycles (number provided by Phone INFO ★Samsung). I knew that after 400-500 chargings using the same battery is dangerous. So I moved to amazon.it and I searched for Anker battery and I found nothing. I mean, there is the item on Amazon, but there are no more batteries for Amazon.it. So first of all, which battery is the best at the moment? Is better a genuine battery from Samsung (there's a €13 battery right now) or another battery (I don't want to pay more than €10-15 for a battery, because I have no money - the bad thing of being 15)? So, I know that Anker has a great value for money, but as I said there are no more, otherwise I must buy them from Amazon.uk. Is it safe, and convenient? After that, my final question is:
which battery (that I can receive in Italy) is better for my SM-N9005 Note 3?
Thank you, Ivan

I got my Note 3 2years now. Charged it 2874 times. Still the 1st battery I'm going for a orginal Samsung for 10euro.
On ebay like 20 dollars the note 3 replacement battery. Size 4200mAh and yes the difference between thr orginal and 4200 is tested out, much longer life. But one thing i noticed on orginal battery, when your phone shuts off due to low power you still have power to turn on and off maybe 15 more times. With this 4200 though it doesnt play like that, when phone turns off you cant turn back on
Holy the phone i bought from someone has 4580! well minus mine probably. had it for a month
I've just bought this below battery for my 2 years old Tmobile Note 3 for the past 3 days. So far so good. My Note 3 is on Note 5 port ROM and I tested this new battery for 3 days by having 5 widgets running on my screen, 2 email accounts syncing every 5 minutes, facebook is always logged on, location is enable, Data and Wife are also enable, 2 group texts for 10 and 6 people with moderate to heavy texting. The new battery lasts me from 8 am right after full charge thru midnight with almost 2 hours remaining. This battery comes with the new back cover and it looks good. I think you should get this.

Placed new orginal battery in my phone today.. checked with the app and counter was not on 0 but the same as with the old.. so I don't think that samsung info app isn't accurate
Phone Info is like a km counter, it show how many times you charged the battery, but not how many times you charged new battery. So it's normal

Bro please change battery now, we're talking about your life, in China and Europe a lot of people reported explosion of batteries, fortunately the most of times when they didn't have the phone with them, but in places like a table, a bed... Nokia, LG, Samsung, Oneplus... all these trademarks reported battery explosions, and I don't want imagine how much with Chinese products

Don't know what battery to get, i don't wanna get those bulky ass batteries that screw with the phones size
Just get original one. Is 10euro/$ .
With old stock battery I lost 8% over night.
With new stock Samsung last night -1%

I bought a new genuine one, getting 6h+ SOT with Aryamod.
Well the app only says charger connector counter, doesnt mean its a full charge cycle. I have 2900+ on mine.
If you can find one in Italy (great company), search for 'MPJ Note 3'. I highly recommend both their 4500 and their 7500mah batteries, and other threads on this forum wait them.
Anker and Mugen as well are both highly respected (although I've not used them myself)
And obviously, the original is dependable.

yes the best battery!!!
I use jubatec battery two days ago...
thanks for the info
+1 for original Samsung battery
Just checked. This counter shows how many times USB cable was connected to the phone. Remember the number. Plug it in 2 times reload the app and see it will we +2 on the counter/ Mine is aboit 2890 have mine for 2 years now/
got anker 3200 mah for about 3 weeks now and it is great.
Polarcell, best choice. I got one couple weeks ago. SOT easy go 6 hours with slimrom 5.1.1...

Battery life and usage

well every time a new phone comes out, early reviews are mixed with some having terrific batter while others are having a dreadful one. Theres only one way to have a scientific approach to measure a battery life, and it is to use a standardized test on the phone with most commonly used settings on and others off and no applications installed etc. Since that is hard to do lets just use a poll.. Whats your uptime, SOT and some major setttings...like below
UPTIME: 24hours
SOT: 6H15mn
Connectivity: LTE
Settings: Auto brightness, gmail sync
also put up screenshots of the battery tab so we can see the usage, not just people just starring at a black screen
thanks for voting guys but its also crucial that you post the infos as described that way we can help fellow members with bad battery life
Can't upload photo for some reason.

This can't be accurate; the GSM signal power and quality differs for every user and it's an important factor to consider. If I use my phone in two different locations in my city I'll have different results.

Yes there are many factors that impact the battery life unless we all run the same battery benchmark on airplane mode with default configuration and no apps installed, battery life is not comparable but it's just to get an average
The new chip is just bad. This won't get fixed.
You can try to use a custom battery savings mode and just enable the CPU limiter, it'll cap performance to the S8 but battery will be quite a lot better.
I can get a day or more but its no match for the Mate 10 Pro I had before
Sorry but won't post any screenshot as I have to put in charge everyday around 3 pm, unplugged at 7 am, to make sure battery will last til the end of the day =(
My previous 3 phones were S8+, Note 8 and Iphone X, all I can say is that S9+ battery life is much worse compared to the 3 of them.
Expecting an update to fix that, if it doesn't come in the next 10 days I'll return my handset.

You realise leaving it charging over night knackers the battery because it keeps trying to top up which over time puts a lot of extra wear and tear on it

You realize I've been doing that for 20 years with no issue at all?
Sorry if my first post was not clear : I put the phone to charge (induction) when going to bed around 1am, unplug it in the morning around 7am and have to do a complementary charge in the afternoon .
very good
The more it consumes internet over mobile data the power decreases. However, good at all

I don't want to disappoint you. But my previous phone was S8+. Unfortunately with the official update to Oreo the battery performances was a little bit worse than S9+.
Agree with the fact that with Android 7 Galaxy s8+ had a better battery life. But with Oreo... that's another story.

Bump this as some users are reporting very bad battery life while most can achieve 5-7 hours easily please participate in the poll
I have the SD variant S9+ and I'm in the very bad battery life camp.
I am also in the bad battery camp... I can get about 2-3 hours of SOT before it just craps out and I just spent 800$ on this thing. I'm ready to return it myself.
I'm on exynos and really enjoying my battery life. Anywhere between 5.5 - 7.5hrs sot depending on how I use the phone.
Rocking on 6 or 7 hours sot with all social apps, pubg mobile, Twitch, YouTube, discord.. Exynos version. Who has bad battery should move to Apple because u can't even make your android smartphone have a good battery.

This is better SOT than I've ever gotten from any smartphone I've owned. 5 hours SOT and still 38% left.

Standby time is amazing, too. 9 hours overnight used only 5%.
The battery life for this phone is good. The standby battery life is not great. I don't get a good signal at my job, so when I get in I cut off my data. With the data off, the phone is still draining battery.
However, if I'm in a good signal area or on Wi-Fi, I can get 6-7hours sot.

Doesn't charge the battery over 80%, is that true?

I installed accurate battery app, and it says that is better not to charge the phone more than 80%. I read about it in other places, is that true?

I've never heard of this before, but I've looked up the App.
It looks interesting, and doubly so since it might help determine how much capacity my old HTC 10 has lost. It reaches 25% and switches off and just bootloops after that (which I know is a battery issue, I'm just curious to see statistics, since the phone itself seems to be unaware of any issue).
As far as only charging up to 80% goes, I've never heard of it. The only thing I've heard is that you should never let the batteries completely discharge. Getting charge back into them might be a problem.
And anything that tells you the "memory effect" could he a problem is wrong. It isn't. Only on old Ni-Cad batteries etc.
Best not to leave it on charge once full as that keeps pumping and putting unwanted wear and tear on it
If you're going to be absolutely OCD about battery health, the absolute ideal percentage to keep them at is between 40% and 80%.
But in real world usage, you're going to get absolutely minimal (no) benefit from doing this. It's just not worth it.
All you need to do is avoid discharging the battery completely. Don't let it run out to 0%.

I've been doing this since owning the S9. I've only depleted the battery once, rarely let it got below 30%, and charged to 100 probably about only 5 times. I can't quite testify real world benefits yet (and probably won't for long since this is theoretically for long term benefits) since it's my first time picking up this practice with this phone. However, the frequency of my charge has been concerning me a little. Any other thoughts this or charging this frequently?

Daily Express. Same rag that posts that the UK is going to have a heatwave in summer and the coldest winter for 100 years, *every year*.
Does charging overnight have an effect on battery life? Yes, but the effect is mostly negligible.
My youngest son is currently using my 3 year old Nexus 6p. Throughout its life it has been on the charger all night, every night, and also topped up during the day.
It is still on the original battery and still gets around 4 hrs screen on time a day.

Doesn't matter if you're a Guardian reader the fact remains and its covered on various sites, I notice you only decided to pick one link!
My son had my old S7 Edge and wrecked the battery

That's because there are loads of links that dispute it!
Facts are you said that leaving it on the charge will continue to "pump" charge into the phone, when in reality the charging circuits switch to trickle charging once 100% is reached!
As far as your S7 goes, without knowing your usage case I can't say for certain, but chances are the problem is more likely related to completely discharging the battery (which kids are wont to do) rather than leaving the phone on charge.

That's i wanted to know. I use my phones for years so I don't want that the batteries die faster. I want to keep them alive as max as possible. Anyway, I read a few things and it seems that this "40 to 80%" thing is true. I'm a little concerned [emoji28]

Some discussion here and elsewhere that Accubattery isn't that accurate. I've used it for a while on both S8 and lately on S9+. Accubattety says my 3 week old S9+ is down to 95% capacity already. Whatever, after reading on reddit and xda decided to uninstall it. As a result standby time has improved. I've no hard proof other than the battery has more left in it on my average day. Battery apps - waste of time I personally think!
As to keeping above 40% and below 80% then sure it is better for battery health. I even started to do the same myself. Like the last time I tried it on my then S8 I soon got bored of the hassle of topping up. Gone back to sticking it on charge pad at none fast charge overnight. Pretty much what I've always done. Battery never seems to take much harm. Should battery lose a lot of capacity then there's a fair chance I may be upgrading phone by then or just have a new battery fitted.
Charged previous S8 overnight for a year with occasional run to flat and capacity was at 98% according to Accubattery. Danger of being OCD over battery charging, just charge it right up and enjoy the phone!
