Umi plus E battery from 40% to 10% in seconds

hugo.oliveira

I had this problem with about 30% baterry, but it started to become a bigger problem. It went up to turn off at 40% or more, and then it just drop down frm 9x% to 6x% and a few moments later it turn off as well.

Now it's completely unreliable to leave home with this phone in a need, because it can turn off suddenly with 100% of battery charge.

My problem is the battery itself for sure, since it started to open the phone because it's apparently swollen. I'm looking for a new battery, but I not sure that this one is the same as the original battery, can anyone confirm please?:

Pay attention to Plus E's sides if it's not starting to open up just like mine, I may be the battery swelling too.

Hello, I have the same problem with the battery, it collapses when I get to 30% I had hopes with the 7.0 update but it seems to be true that there is no update, it is unfortunate because it is totally true that it was announced in its promotion, it was one of the reasons By which I decided to buy it, if true this would be a fraud!

To the UMI Administrator "bencebacsi":

Please note that all the guys complaining here, they are not trying to offend your company or insult it. We all have an issue and we are looking for a solution.

1. Regarding the statistics. So far, at least 16 people (according to my counting) complained here in this particular thread about this same issue. So as a a company, you should take the issue more seriously and investigate the problem yourselves. My brother and I bought two copies of the phone and have the same issue. This can't be pure luck. And probably you, as a company, do not care much because you do not receive much complains, but as a user, I (and everyone does) think that I am the most important person in the world to myself, so having this issue is pretty serious. I won't just sit there and say "Oh, this is not a big problem because it is not happening to everyone" because I care more about myself than about these so-called "others.

2. This leads to my next point. Here is a small hint: 96% of the people who have an issue with a given product won't complain [source 1], not to mention going to your forum and making an account to tell you about it. So if the people who complained so far in this topic is not enough for you to start taking the matter more seriously, then when would that ever be? I am checking on other websites [for example youtube comment section for some of your videos] where people usually have accounts, and you will see some people complaining about this issue. So to conclude. This is not a tiny little problem that happens very rarely. This is AN ISSUE.

3. You promised in one of your campaigns (that made me buy this phone) to release the Android 7 for this particular phone, and if you are still faithful to your promise, I think it's a good idea to figure out the solution of this problem and releasing it with the update.

4. I personally would prefer to have an indicator that tells me that I have 20% left while in reality I have 40% left, rather than an indicator that tells me I have 40% left when I have only 1% and my phone dies 1 minute later.
I think an OTA is needed soon. You can even re-calibrate the battery calculator so that it considers 30% as the absolute 0 (or say 1%). That way if a user has 1% left and his phone is still running he won't complain much and a user who have 20% (previously 50%) knows that he should recharge his battery soon.

Please do not count on users to investigate these problems. Do your own "honest" experiments and figure out a way to fix the problem on your own test units. I think you are not supposed to ask a user to root his phone and change something that could damage his phone. (again I am not offending or attacking you.. I am only a user who wants a solution).

Thank you for your understanding!

Dear Users,

Until now 14 users (plus malanore's brother) reported a quick battery percentage drop at 40% or below in this thread. We still cannot reproduce this issue on any of our test devices, so we ask you to help our work with recording log files as the video below demonstrates it.

1. Please start to log your phone starting at 40% of battery power and stop it before your phone turns off. Don't connect your phone to charger or computer USB port while the logging is running.
2. Archive the mtklog folder into either a zip or rar file, upload it to a web storage and send its link to ben@91umi.com. Please don't share your file publicly since it may contain personal data.

Using the provided log data, we will investigate this issue and offer a solution as soon as possible.
Thank you for your cooperation.

Thank you for your reply.

I appreciate it. It has very clear instructions that do not involve any "dangerous" operations such as rooting the phone.

I have only one question, and I would be grateful if you can give me an answer:

- Since the phone goes super fast from ~35% to 1% then shuts down, I am not sure if I can catch the recording and stop it before it turns off. So I want to know if the logs are lost if the mobile turns off, or I could simply send them after I charge my phone and turn it on.

In both cases I can try and get them today. I just want to know if I should be careful.

Thanks in advance for your understanding.

The log files are baing saved continually, so even if your phone turns off suddenly, the result might be useful.

Hi Admin,

Let me make these points very clear

1. We are not testers for your product, you cant ask us to do this and that when we have our own busy schedule.
2. we are consumers and when so many people are complaining and you still asking us to do logs and stuffs is just not right.

we are not asking you to release A7 or give us new features, we are just asking you to fix bugs that are already existing and make it better for us consumers.

Hello, I have the same problem with the battery, it collapses when I get to 30% !!! Umi get your act together and Fix this Problem or I will
be demanding a Total refund this is un-acceptable !!!!

I sent the files to the mentioned email. it contains a link to this thread and an attached file, so it might go to the spam folder!

I am looking forward to seeing what you can do to fix the problem. Under other conditions, I would not share private information, so I am expecting to see some results, other than promises.

The phone is overall doing its job, and I have no big issues with it (even the bugs and screen precision thing are not really that big of a problem). BUT, this problem (the battery thing) is just ruining the entire experience, and I am back to using my old iPhone 5s as my primary phone, just because I can't trust this one anymore. It just dies whenever it feels like it, and that's just SUPER ANNOYING!

One of the reasons I wanted this phone over others is the promising battery (4000mAH) and guess what?? it turned out to be the biggest issue!
