How many charging cycles for iphone 4s

Brad, working the iPhone battery harder and more frequently does not degrade it's charge capacity any faster. In fact, it keeps it healthier. Sure, you might not get as much time between charges, but we're not talking about how much use you can get out of a single charge. We're talking about how much life you can get out of the rechargeable battery. I once thought as you do, but I have since converted to a new form of iDevice battery-conservation.

I used to try to use my batteries very sparingly, figuring that I would slow the battery's inevitable decline into shorter life. But my practical experience has proven otherwise. I have been using my 4S battery like there's no tomorrow and my 3rd Gen iPad battery severely less, sadly. Granted, the iPad battery is much larger and typically gets more usage per single charge, but the principle still stands as the iPad battery cells are still seeing a relatively proportional difference in use than the iPhone battery cells, even if the device itself sees more use.

After all, we're discussing battery cycles and not usage time. Make sense? So, are you ready for the numbers? Keeping in mind the age and number of cycles, the iPad has lost 6. I run my phone hard obviously, with cycles in less than one year ; I don't baby the brightness, I play videos a lot, my phone gets hot in the sun, and I am totally lost without my google maps. Wanna know why? Two main reasons: 1 Time. Part of what kills a battery is good ol time.

My battery is still young in that respect. Look at my iPad numbers. It has FAR fewer cycles, but it's 6 months older. You see, Apple figured the average user would rack up cycles in roughly two years, so that explains their quote. Reason 2 Exercise.

Like a muscle in the human body, with routine exercise, it stays fit longer. Without regular use, like a muscle, it atrophies. The more you nurse your battery and try to prevent it from working hard, you are denying it the frequent exercise that those little cells crave.

Once again, compare my iPhone battery to my iPad. Lesson here: use your battery without discretion. After all, it is a mobile device. I used to constantly worry and whine about my battery life, but now I am free and I get out there and use it to the fullest. It was designed to be untethered. If my lifestyle demands heavy use, then doggonit I'm gonna buy me a battery case and get more out of it. In the end, it was always a consumable product, and I've learned to get the most out of it and enjoy it.

At the time that I wrote that reply, here were my numbers. Thanks you. Actually, the 4S is rated at hours of standby time, whereas the 4 is rated at hours. So no, not every iPhone has longer life than the previous one. Keep in mind, I had my 3gs running on iOS 5 before upgrading and I still have it and was continuing to use it as an iPod.

So other than Siri, there should be no software difference between the two so it should be possible to remove the software as the culprit unless there is something about Siri that runs constantly and is draining the battery. And I think there is a third potential issue that is "the iPhone 4s has worse battery life than the 3gs", be it due to the A5, the multiband cell radio or something else.

Dismissing that as a possibility seems rather naive. The phone gets quite warm when the battery is draining. Much more so than I experience when doing anything else. This may be a red herring, but my phone won't sync. I don't know if this is related, but doing either a restore or trying to sync with iTunes while connected to a MBP fails. I can only get things to work with "Transfer Purchases". This may be an unrelated problem though I hope it isn't as there is a chance I'll get a fix for the battery problem.

Without doing that first, your guess is as good as ours as to why you're not seeing a lengthy battery life. Took it in, got a replacement phone and have had excellent battery life since.

I found a car charger but one of the reviews said make sure you know how many amps you need to charge your product because it would not charge his apple product. Anyone have an answer for me? Thanks in advance. Darkstar Administrator Staff member. Skull One Super Moderator Staff member.

The nominal amperage needed is 1. It then purposely slows down to half or more that charging rate to preserve the batteries longevity. Skull One said:. Click to expand Jhyler12 said:. Joined Nov 14, Messages 2 Reaction score 0.

So if I have an iPhone 5 and I'm looking to get an external battery pack and charger and it advertises that it has mAh, what does that mean in terms of charging the iPhone. The mAh means the capacity that the charger can hold and recharge. The iPhone 5 I believe has a designed 1, mAh just like the 4S. If the external battery pack holds mAh, that means it can recharge your iPhone about 3. Joined Feb 12, Messages Reaction score 3.

So I've purchased the Battery charger. One is labeled Out 1A the other is labeled Out 2. Does it matter which one I plug either the iPhone or the iPad2 into other than how long it will take them to charge, or is it wrong to plug in one or the other to the 2.
