If your Samsung Galaxy S6500 (Galaxy Mini 2), Galaxy S7508 (Galaxy Ace Plus) or i6500D has started dying before lunch, you’re not imagining it — the EB464358VU battery that powers these phones simply wears out. For a classic removable-battery smartphone, though, that’s good news: the fix costs very little and takes about a minute.
This guide covers what the EB464358VU is, why runtime drops, why a battery stops charging, how to tell if it’s genuinely dead, and how to get the most from your phone’s usage.

A few important notes before you buy:
- This is a 3.7V Li-ion pack. Never substitute a Ni-MH or Ni-Cd battery — the voltage and charging profile are completely different.
- Match the part number, not just the phone model. Confirm that the battery code on your current pack reads EB464358VU (some listings also reference EB464358VUBSTD).
- The EB464358VU family also fits related models such as the GT-S6500 / GT-S6500D / GT-S6500T, GT-S6102 Galaxy Y Duos, GT-S6310 Galaxy Young and GT-S6802 Galaxy Ace Duos — but always verify your exact variant.
Symptom 1: Battery Life Is Getting Shorter
The most common complaint with an ageing EB464358VU is reduced runtime. These phones originally shipped with a 1300mAh cell rated for roughly 11 hours of 2G talk time. As Li-ion chemistry ages, usable capacity fades — and then the phone starts dying at the worst possible moment.
Watch for these patterns:
- Runtime shrinking: a battery that once lasted a full day now dies by early afternoon.
- Sudden power-offs: the phone shuts down abruptly, sometimes at 30–40% on the meter.
- Unreliable gauge: the battery percentage jumps around or sticks before collapsing.
- High self-discharge: the phone loses charge noticeably even when switched off.
Rule of thumb: when runtime falls below about 70% of what the phone originally delivered, a fresh battery is cheaper and easier than living with the constant anxiety.
Why it happens: every full charge/discharge cycle removes a small amount of capacity. After 500–1000 cycles — easily reached on a phone charged nightly for a couple of years — the pack is well past its useful life.
Symptom 2: The Battery Won’t Charge
Battery not charging is the second big red flag. Before you blame the battery, work through the possibilities — the cause is sometimes the charger, the cable, or a confused phone rather than the cell itself.
| What you see | Likely cause | What to do |
| No charging indicator at all | Bad contact, faulty charger/cable, or dead battery | Clean the battery terminals; test with a different charger and cable |
| Charges briefly, then stops | Deep-discharge “sleep” state or software glitch | Remove and reinsert the battery to reset the phone, then retry |
| Gauge stuck at a low % regardless | Low-current CPU power-save mode blocking charge | Pull the battery and reinsert it to “wake” the charging circuit |
| Charging takes longer and longer | Capacity loss / rising internal resistance | Replace the battery |
| Shows full, drains in minutes | End-of-life cells | Replace the battery |
Two easy resets worth trying first:
- Clean the contacts. Wipe the battery’s gold contacts and the phone’s terminals with a dry, lint-free cloth — oxidation and pocket dust cause surprising numbers of “won’t charge” faults.
- Pull and reinsert the battery. On these older Samsungs, the phone can slip into a low-current state where it refuses to charge. Removing the battery, waiting 30 seconds, and reinserting it often restores normal charging.
If a known-good charger still won’t charge the pack, or it charges but holds almost no runtime, the battery has reached end of life.
How to Tell If Your EB464358VU Battery Is Actually Dead
Run this simple three-part check — no expert tools required beyond a basic multimeter.
1. Visual inspection
A healthy pack looks clean and flat. Any of these means it’s finished:
- Swelling or bulging — the most dangerous sign. The battery may no longer sit flush in the phone, or the back cover pops off. Stop using it immediately.
- Cracks, dents, or bending — physical damage can compromise the internal separators.
- Corrosion, leakage or white residue around the contacts — the electrolyte is escaping.
- Discoloration or a burnt smell — evidence of overheating.
⚠️ Safety first: never puncture, crush, bend, or heat a Li-ion battery, and never try to “revive” a swollen or leaking cell. Recycle it through a certified battery-recycling point.
2. Performance check
- Does it still get you through a normal day of use?
- Does it charge fully, or stop short of 100%?
- Does the phone get unusually hot during charging or calls?
- Does it power off abruptly at a high percentage?
If you answered “yes” to two or more of these, the battery is on its way out.
3. Electrical test with a multimeter
Set the multimeter to DC voltage and measure across the battery terminals:
- A fully charged healthy cell reads close to 4.2V.
- A healthy nominal reading is around 3.7V.
- A reading that has fallen well below nominal, or that collapses under even a light load, confirms the pack is worn out or deeply discharged.
At that point, replacement is the only safe and sensible option.
A Word on Charging Cycles (and a Common Myth)
Li-ion batteries do not suffer from “memory effect” — you don’t need to fully drain them before charging. In fact, deep discharges are what shorten life. A few practical points for the EB464358VU:
- New batteries: run 2–3 full charge/discharge cycles to calibrate the phone’s battery meter.
- Don’t deep-cycle routinely: top up when convenient rather than always running to 0%.
- Avoid overnight charging as a habit: unplug once full.
- Store cool: heat is the number-one enemy of Li-ion capacity. Never leave the phone on a sunny dashboard.
Where the Samsung S6500 / S7508 / i6500D Is Still Used
These are 2011–2012-era entry-level smartphones, long discontinued — yet a surprising number are still in daily service. Common scenarios for keeping one alive with a fresh EB464358VU:
| Scenario | Why battery quality matters |
| Backup / emergency phone | A working spare in the drawer is worthless with a dead cell; a fresh battery makes it dependable. |
| Elderly family members | Simple, big-button-friendly usage; a phone that lasts the whole day avoids mid-day panic. |
| Kids’ first phone | Cheap to replace, no loss if damaged — but it still needs to hold a charge for safety calls. |
| MP3 / media player | Repurposed as a music or radio device (FM with RDS supported) with no SIM. |
| Alarm clock / bedside device | Runs overnight reliably on a healthy battery. |
| Two-way / walkie-style comms | Some users pair these with apps for local group calls. |
| Nostalgia / collector use | Keeping original hardware fully functional for a classic Galaxy collection. |
| Retail, warehouse or field backup | A rugged, cheap standby handset for staff who only need calls and texts. |
For all of these, the calculation is the same: a low-cost 1300mAh EB464358VU replacement costs far less than a new phone and restores the device to full usefulness.
Why Choose a 1300mAh EB464358VU Replacement

How to Make Your EB464358VU Battery Last Longer
- Use only the correct Samsung charger and a good-quality cable.
- Avoid routine deep discharges; top up before the phone hits 0%.
- Don’t leave it plugged in for days at a time.
- Keep the phone and spare batteries away from heat and direct sunlight.
- Run 2–3 full cycles to calibrate a brand-new battery’s indicator.
- Keep spare batteries away from metal objects that could short the contacts.
- If storing a battery long-term, charge it to about 50% and recharge monthly.
Is the EB464358VU compatible with my Samsung Galaxy?
It fits the Samsung Galaxy S7508 (Ace Plus), S6500 (Galaxy Mini 2) and i6500D, as well as related variants such as the GT-S6500 / GT-S6500D / GT-S6500T. Always verify both the phone model and the battery part number (EB464358VU) before ordering.
How long should an EB464358VU battery last?
Expect up to roughly 11 hours of 2G talk time per charge on a healthy pack, and around 500–1000 charge cycles over its lifetime. After that, runtime declines noticeably.
Can I use a Ni-MH or Ni-Cd battery instead?
No. The EB464358VU is a 3.7V Li-ion pack and is not interchangeable with older Ni-MH or Ni-Cd chemistries.
My battery won’t charge — is it definitely dead?
Not always. First clean the contacts, try a different charger and cable, and pull/reinsert the battery to reset the charging circuit. If a known-good charger still fails, or the pack holds almost no runtime, it needs replacing.
How do I know when to replace rather than repair?
Replace when runtime drops below about 70% of original, when it won’t hold a charge, or when you see any swelling, leakage or corrosion. A swollen Li-ion battery must be retired immediately.
Is it safe to keep using a swollen battery?
No. A swollen pack is a genuine fire and injury risk. Stop using it, do not charge it, and dispose of it at a certified battery-recycling point.
Give your Samsung a fresh start. Stop charging twice a day. A 1300mAh EB464358VU replacement restores full-capacity runtime to your Galaxy S6500, S7508 or i6500D — and installs in under a minute. Check your model and part number, then upgrade today.
