Seidio external charger

I bought this: http://goo.gl/70Els
I'm wondering if it will solve the bump charge issue and will charge the battery fully without having to go through hoops to just charge a battery!!!
I'm tired of being at 90% after ten minutes after a full night charge!
Thanks

Very doubtful. Your best best is the kernel being developed in the dev section with increased charging.

My question has nothing to do with the phone itself because the battery is not in the phone when its charging, it's sitting in the cradle. Nothing to do with the phone itself. Do you think the cradle will charge the battery fully and completely.

I've got the charger mentioned as well. I just see it charge the battery "normally" to 100%, and if needed over the next ~xx(x) hours or so, another trickle at low mA will be applied. That isn't the same as this "bump charge" that is always referred to here.
If you turn the phone off and charge, it'll charge just like the charger (Seido) to 100%.
There's lot of good info about LI batteries like this writeup: http://batteryuniversity.com/index.php/learn/article/charging_lithium_ion_batteries
Anyway: I thought the main gripe about the DINC charging technique is not anything about the technique, but that it always runs the phone off the battery, rather than using the USB current when it's plugged in. Most phones use the USB (or whatever tech) to a) charge the battery and b) run the phone. Of course if this is HTC's method, then you'll very rarely unplug at 100%.
The rate of battery consumption, regardless of % starting point is more of an issue for me. Using all the SENSE/HTC/VERIZON stuff is a losing proposition more than not having 1-9% of the full capacity at 'go' time. As soon as I rooted, I dumped every app and service starting with HTC*, VER*, *sense* and battery life improved by a great deal. Yeah, I don't care about social networking (well, aside from a forum or two ) -- But I enjoy most of the other phone functionality.

The charger's fine, it's the battery that troubles me
I have the charger, too. Works fine. Does not require "bump."
But the battery (the 1750) that came with it has failed to impress me much, with a tendency to overheat. Frankly, since I rooted and started using SetCPU to underclock with screen off, I've been using the stock battery.

[Q]Okay to charge battery beyond 100%?

When it reaches 100% in the Samsung car dock it tells you to take it out of the charger. Also someone told me it's better the less juice the battery has before you begin charging it.

You really can't overcharge lith-ion batteries. They all require active charging, so once it's full it's not like it keeps drawing power. I don't think the amount of battery left, either, has any bearing on charging it.

i always leave my phone plugged in at night
so yeah, it does waaaaay over charge past 100%
it'll stop charging when it reaches full

how fast can Arc S charge?

how fast can Arc S charge?
how many Voltage recommanded for the charger?
is 1000mA max support, can it be higher like 2000mA?
thank you

All I know is that the default charger is 850mAh, and that already chargers pretty fast. half-full in an hour.

do you think it can be faster?

i would say mine charges full in an hour

charge current is programmed in phone's firmware below 1A for AC chargers and below 500mA for USB (don't remember actual values), so even if a 2A charger is used, charge time will not vary.

Mine goes about 1% a minute, I find it good enough for me.

Full charge takes about 1,5h so for me it's not long. But comparing to Xperia S and 0,5h Arc S charge takes ages

When it gets to 90% or maybe even 85%, it slows down its charging, and displays the LED as green, it then continues to charge, this is the economic techniques of the charger, at least that's what I remember from the manual. So it saves energy as most people charge their phone at night, as it gets plugged in for longer periods of time.
This was the first device that introduced me to that concept, the iPhone 3G I had before focused on faster charging. I am unaware of any other products that use green charging methods, however I'm certain other devices will do.

charging a lithium based cell requires a first step using a constant current supply, until voltage reaches 4.2 volt; beyond that point, charging switches to constant voltage, providing the last 10% or so of charge to the cell.
every li-ion charger does so, but someone signals "cell charged" (i.e. green led) when charger actually stops supplying current, others when transitioning from constant-current to constant-voltage mode.
and if that last 10% of charge is not so vital for you, i suggest to disconnect charger as soon as led turns green, because at that high voltage, corrosion of battery's anode is faster and so life of cell and it's capacity is reduced on the long run.

MYTH NO. 2: Overcharging your lithium ion battery will reduce its battery life
One of the most common myths that we have heard about lithium ion batteries would be the need to plug it from its charger after being fully charged, since overcharging the battery/device will reduce its battery life. The truth is, lithium ion batteries cannot be overcharged or can be reduced of its battery life through overcharging. What’s good about these batteries is that that already have built-in circuits that will cut off the power once it has been fully charged.
However, it is a good idea to unplug or remove the battery once it has done charging because the heat from poor ventilation or from charging will cause it to blow up. Another reason why this is an important note worth remembering is that batteries discharge faster when heated thus, reducing its lifespan.

that it's true, and is a residual myth from the age of stupid charger that went on charging forever after 100%.
perhaps I was not talking about overcharging, but to terminate charge before the constant-voltage part (at about 90%) if you want to slow down capacity reduction and so prolong battery life.
life of li-ion cell is optimal at 40% charge, but obviously a cell kept at 40% is useless :laugh:, so only thing I can suggest is to avoid reaching full charge if you can.
it's a form of perfectionism, let's call it so

I undervolted my phone, turned off WiFi, sync, brightness and put it on powersaver, charged at 1% a minute which is much faster than its normal charge. Good for me to know, obviously turning the phone off is basically the same

I do it when I can't get a full charge before bed; but I also wake up 2-3 times per night and tend to unplug it once I notice it's at 100%. I've read that once it reaches 100%, if it stays on charge for a certain amount of time it will switch to battery and drain, then charge back to 100% after a certain percentage is drained. I would say that's the case as I woke up one morning and the phone was at 92% charge and was in the process of charging. Battery info said it was charging on AC and the graph showed it went to 100% then back down.

I do use that guide. My signal is terrible and is what drains my battery. I really don't believe that is related to any app running wild and draining my battery because from completely dead to 100% takes about 2.5-3 hours with me using it, WiFi on, brightness at 100%, etc; I can also easily get over 2 days without a charge with light use... It would be more but my lack of signal accounts for an almost 1.5% per hour idle drain. Good signal areas I'll drain less than .5% per hour with no use/app changes outside of having a strong signal.

Weird...
When your phone charges to 100%, your phone knows to stop charging, mine always stops charging when is says "reached 100%". I just leave it on the charger and it stays steady at 100 until i take it off.
It shouldn't effect the lithium ion, either.
I thought that was the special thing about lithium ion?
They don't wear down?
Idk, could be wrong.

I always leave it charging when I fall asleep. And if, IF I wake up in the middle of my sleep and see that it's at 100% I'll unplug it. If I don't wake-up I'll just leave it charging until I wake up. Been doing that since before I even had a smartphone and never had any problems. Then again I do switch phones every year

A bad signal will definitely drain your battery. When I know I am in an area without signal and will be there for a few hours I turn my phone's power off so I have some battery left when I need it.

Bought some cheap batteries on Amazon, I charge whenever I want, however I want (typically overnight, all night). If I ruin the battery, so be it, I can just pop it out and replace it in 5 seconds. This is the real advantage of having a removable battery.

I've always left my smartphones on the charger overnight. Seven years going and haven't had any issues. I do tend to replace my battery after 9-12 months of use though.

This sums it up. Per the article linked earlier in the thread about charging li-ion, it sounds (relatively) trivial for the device manufacturer to implement a charging cut-off after the cells reach a specific voltage level. Once the cells drop to a certain level they're safe to charge again, and the cycle starts over. I don't imagine it's great for the battery to sit on that recharge cycle, but it's not going to over-charge and become a fire hazard.
I imagine external battery chargers might be a little different. That $3 battery & charger from eBay isn't going to have the same safety regulations as a major manufacturer like Samsung.

An interesting tidbit from that article.
Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery.

I get the general concepts that the article presents, but it doesn't really address any advances in charging methodologies that newer devices could add. It reads like it was designed for 'dumb' devices such as cordless phones, rechargable power tools, etc. For instance, it says never to charge with the device powered on. Yet Windows Phones (at least my Lumia 800) won't charge with the device off...plugging it in automatically boots the phone up.
Our phones obviously have more advanced power circuitry, such as being able to hold the power button in and have the device power cycle no matter what state the phone is in, and I assume it applies to other parts of the phone as well.

Is it bad to constantly top off your battery?

Note 7 is my first foray into wireless charging. I figured it would be useful at work for me as I can spend random amounts of time away from my desk throughout the day so when at my desk I can drop it on the charger and then grab it when I need to go. I just wondered if thats bad for the battery?
I already did a full drain and then full charge from there and even that I'm not sure if it's still beneficial to do. But with a non removable battery I want to make sure I'm not doing more harm than good and shortening it's life by having it on and off thw wireless charger often during the day. Thanks.

Its not bad, its actually recommended. Keeping the battery as high as frequently as possible will help in the long run.
Using it while its charging isnt so good though.

From my research into battery life what you write is incorrect. There are other threads on this very subject where I precise my findings.

Apparently keeping the battery between 50-80% is the ideal scenario. It's probably ok to change to 100 but leaving it on the charger once it's fully juiced makes the battery heat up too much which is bad for it.

There has been research that suggests it is better to charge the battery from around 40%-to about 95%, never full.

I looked at some of the research people have mentioned and it does seem that between 40 and 80% is the sweet spot on the Lithium Ion batteries. It says not to charge to 100%, but that the phone is smart enough to stop charging ones full to prevent overheating. But regardless I suppose leaving it plugged in overnight isn't the best idea.
But in my case it sounds like multiple charges throughout the day isn't bad on the battery as long as it keeps it in the 40-80% range? I can manage that, just wanted to make sure multiple small(5-10%) charges throughout the day wasn't also shortening its life span.

Hard to say I guess. I was the drain and fully charge guy. Never any issues. My wife is the opposite, she should constantly top it off or close and her battery would drain faster than mine. Eventually hers would die very early. So who knows.
Always been like this with all our phones

I know some firms in the past have built in charge counters in batteries so you could only charge the X amount of times, but that was a fair few years ago and things have moved on since.
but my phones I have charged them multiple times a day and my Xperia Z1 that I got on launch day is still in use by a friend and still has near perfect battery life despite being charged some time multiple times a day and always being left on charge overnight every night. (so thats for about 3 years now?)
my S6 I have ran on the wireless charger since I got the phone on release day, every time I went in the room I chucked it on the pad to keep it charged up, the phone still works and charges flawlessly, the Samsung charging pad unfortunately wasn't as up to the job as the phone was and died last week. but no big loss as I want a fast charging one after I get my note tomorrow.

-The less you recharge your phone, the better
-Keeping your phone between 40-80% is the best theoretical solution for best health. But if you are running your battery down to 40%, and charging back up to 80% twice a day, that's still more wear than just leaving your phone at your desk plugged in at 100%.
Or say you keep it at your desk and you have to move around office 4 times that day. So every time you leave your desk and come back, you charge it back from 90% to 100%. 4 x 10% - 40% is still less wear then the guy doing the 40-80% x 2 a day. Less charging overall.

Wrong. Going above 80% is a "high stress" situation for lithium batteries. It isn't bad, but the best charging practice for absolute longevity is keeping it between 20%-80%.

Leaving it on the charger doesn't heat up the battery. It just keeps the battery in that high stress state, and isn't good long-term. If you are doing intense activities with it plugged in, then yes that is a combo for high heat which is bad for the battery.

Not really. Leaving it at 100% all day is not the best idea. It'd be better to let it run down to 20% and recharge to 80%. Unless Samsung routes power directly to the motherboard when plugged in, instead of passing it THROUGH the battery first, it is absolutely better to not keep the phone at 100% and charging while using it, heating it up further, and it is still cycling the power/wear through the cells.
Does any of this matter? No. Unless you keep your phone for 2+ years, you aren't going to notice any difference. Charge it whenever and however you want. The battery isn't going to **** out on you because of how you charge it.

Thought the manufacturer warranty was two years anyway? Android phones are only guaranteed updates every two years so may as well upgrade every two years. If the battery craps out inside that time just warranty it. It's extremely unlikely though.

TOO MANY MISCONCEPTIONS. Let me clear them up !!!!
1) Lithium batteries like to sit around 50% for prolonged periods.
2) It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v
3) It will HURT THE BATTERY MORE to keep using it when it is depleted or near depleted. Lithium batteries DO NOT like to go below a certain voltage depending on specific chemistry formulation.
To expand on this. It is BETTER to keep the phone at 95% than it is to keep it at 5%. I personally would NOT want my battery falling low enough that it gives a low battery indication (usually around 15%)
4) High Charge and Discharge LOWERS battery longevity. Lithium batteries prefer to be charged slowly and discharged slowly.
You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.
5) Lithium batteries do NOT like heat. Again, this is usually caused due to high charge or discharge scenarios.
It also ties in with Fast charge, wireless charge and especially wireless fast charge. Wireless charging is not efficient and energy as wasted as heat.
Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.
I might put this in a new thread.

So basically what you are saying is you the more you use your phone, the more wear you will put on your battery.
100% to 0% drain (100% total) is still more wear on the battery than 80% to 40% 2x per day (80% total)?

100% to 0% drain (100% total) is still more wear on the battery than 80% to 40% 2x per day (80% total)?

Basically yes...batteries have a finite amount of charge cycles.
Charging 2000mah into your battery, whether its all at once, or 500mah x 4, should be roughly the same amount of wear on the battery.
For me, only things i ever worry about is deep discharges and heat. Heat is the worst enemy imho.
Everything else is pretty minor when it comes to wear.

TOO MANY MISCONCEPTIONS. Let me clear them up !!!!
1) Lithium batteries like to sit around 50% for prolonged periods.
2) It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v
3) It will HURT THE BATTERY MORE to keep using it when it is depleted or near depleted. Lithium batteries DO NOT like to go below a certain voltage depending on specific chemistry formulation.
To expand on this. It is BETTER to keep the phone at 95% than it is to keep it at 5%. I personally would NOT want my battery falling low enough that it gives a low battery indication (usually around 15%)
4) High Charge and Discharge LOWERS battery longevity. Lithium batteries prefer to be charged slowly and discharged slowly.
You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.
5) Lithium batteries do NOT like heat. Again, this is usually caused due to high charge or discharge scenarios.
It also ties in with Fast charge, wireless charge and especially wireless fast charge. Wireless charging is not efficient and energy as wasted as heat.
Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.
I might put this in a new thread.

Pretty much covered it here. Good post.
And avoid high heat scenarios as much as you can.

Somewhere in the samsung+ app for note 7, it says always keep the battery between 50 -90 for longevity.

My last phone, an HTC One M8, spent every single night on the charger for the last 2 1/2 years. I would also connect it to a charger in the car when I was driving for any length of time, and that was fairly often as I was traveling regularly. The battery life was not appreciably shorter when I retired it last week than when I first got it.
